‘Fear factors’ and the price for peace of mind

Puzzled by a world in which security often trumps economics, Professor Mark Stewart is undertaking assessments of natural and man-made safety risks to prove expenditure on their reduction isn't always wise - or even necessary.

Professor Mark Stewart 

Stewart's risk-based assessments of terrorism and climate change may be textbook civil engineering, but his findings are far from what you would expect – as is his recent publishing in Playboy Magazine. Making for a prickly work environment and perhaps an even pricklier public reception, Stewart is as unconventional as they come.

'My research can be unpopular at times,' he jokes.

'We're saying there's actually not that much to be scared about.'

While claims of these 'rather limited' safety risks could be cause for confusion in our postmillennial age of media hype and misinformation, Stewart asserts his research is all evidence-based. With more than 25 years' experience in probabilistic risk and vulnerability assessment of infrastructure and security systems, his expertise is equally well-founded.

'Terrorism and climate change are systems, just like motor vehicles are to mechanical engineers and computers are to those in the electrical field,' he says.

'Our fundamental approach is similar too - we break down the systems to understand their different components and then integrate what we think the reduction in loss will be if you have a protective measure.'

Risky business

Stewart's risk assessments have varied applications but all intentionally pose the same question – Not are we safer, but are we spending wisely?

The multiple-award winning engineer recently sought to answer this on behalf of the US Department of Homeland Security, engaging in a joint evaluation of its expenditure with Ohio State University political scientist, John Mueller. The unorthodox duo's efforts were featured on the CNN website and in Playboy Magazine, with their research revealing vast amounts of misspent money, as well as a gap in our theoretical understanding of current risk assessment procedures.

'Assessments nowadays seem to be a process of identifying potential sources of harm and then trying to do something about them without evaluating whether the new measures reduce risks sufficiently to justify the costs,' he explains.

'This means we keep spending billions of dollars without subjecting certain risks to standard cost-benefit methods.'

Cause for pause, not alarm

One of these risks, as Stewart points out, is terrorism. It's also a risk that tends to be catastrophised in places like the United States and Australia.

'Terrorism is a low probability, high consequence event,' he declares.

'There are not that many attacks in the West and there have never been that many, especially when you compare it to the Middle East.'

'There are also more duds than successes out there.'

Stewart has received extensive Australian Research Council support over the last decade to develop probabilistic risk-modelling techniques for infrastructure subject to military and terrorist explosive blasts, as well as cost-benefit assessments of counterterrorism protection measures. Expressly influenced by the events of 9/11, he is simultaneously looking to dispel widely held beliefs about terrorist competencies and opportunities.

'Hijacking during 9/11 was to kill people - not for cash or to peacefully negotiate the release of prisoners like it had been in the past,' he states. 

'It set the benchmark for terrorism, but I think it's an outlier and not a harbinger of things to come.'

'They've since hardened cockpit doors and instructed pilots, crew and the public not to give in without a fight.'

Believing Al Qaeda 'took advantage of these vulnerabilities at the time,' Stewart largely considers the events of 9/11 as a one-off. The Director of The University's Centre for Infrastructure Performance and Reliability remains on high alert though, labelling a growing shift towards improvised explosive devices (IEDs) as the newest hazard of terrorism. He's working with a dedicated research team to break down these individual systems, applying conventional engineering approaches and assessing their overall safety.

Funding faults

Stewart is also currently exploring cost-benefit analysis methods of police and security agencies in the United States. Set to publish his findings in a fourth book, the evidence-based engineer is again looking at what has already occurred, what is occurring, and what might occur.

'I'm asking the same questions,' he asserts.

'How many terrorist plots have there been and could there be in the future?

'How much is being spent to reduce their risk?

'Most importantly, is it worth it?

Suspecting a case of misspent money on unlikely threats akin to that of the US Department of Homeland Security, Stewart is seeking to sensibly calculate the costs of protection, as well as identify the most effective counterterrorism measures.

'We'll always compare it to 'business as usual' he says.

'To avoid overreacting, sometimes the best thing is to just accept the risk and do nothing at all.'

Mapping the winds of climate change

Stewart similarly observes a lot of worst-case thinking in the climate change arena. Also recognising the power these skewed perceptions can often hold over legislators and financial advisors, he is looking to clear up misunderstandings with the help of the CSIRO and a handful of universities.

The team's research is ongoing, and uses comparable risk assessment methods to evaluate the impact of climate change on damage and safety risks to infrastructure, as well as the cost-effectiveness of engineering adaptation strategies. Their multi-pronged approach also includes evidence-based policy and economic theory.

'Again, we're looking at systems and threats,' Stewart says.

'But in this instance, systems are things like houses and industrial buildings, and threats are naturally-occurring, such as floods and cyclones.'

Research is currently being conducted across the country, with Stewart's collaborators at James Cook University responsible for investigating the vulnerability of houses to wind in Far North Queensland, and civil engineers at the University of New South Wales examining heat and the buckling of rail lines. Unlike terrorism, Stewart contends protective measures for these systems don't automatically come with a hefty price tag.

'We've found you can reduce the risk of damage significantly by changing materials,' he affirms.

'It's all about detailing at a modest cost – tying the roof to the walls and the walls to the foundations.'

Mass fear and cheer

While acknowledging the pressure politicians and bureaucrats face on heated issues of climate change and terrorism, as well as the sometimes-unwise actions and expenditures that follow, Stewart is also a firm believer in practical and rational calculations.

'It's one of the reasons I like risk assessments,' he discloses.

'They're transparent so the evidence is there for people to see.'

Hoping a balance will soon be struck between cuts and pay offs, Stewart is similarly looking to standardise risk assessment procedures for a broad range of safety concerns.   

'It makes sense that the public has difficulty with probabilities, especially when emotions are involved,' he remarks.

'But by giving in to fear and spending irrationally, we forgo the opportunity to use those same resources for regulations and processes that can save more lives at an equal or lower cost, such as healthcare and road safety.'

2015Bastidas-Arteaga E, Stewart MG, 'Damage risks and economic assessment of climate adaptation strategies for design of new concrete structures subject to chloride-induced corrosion', Structural Safety, 52 40-53 (2015)

Reinforced concrete (RC) structures are subject to environmental actions affecting their performance, serviceability and safety. Among these actions, chloride ingress leads to corrosion initiation and its interaction with service loading could reduce its operational life. Experimental evidence indicates that chloride ingress is highly influenced by weather conditions in the surrounding environment and therefore by climate change. Consequently, both structural design and maintenance should be adapted to these new environmental conditions. This work focuses on the assessment of the costs and benefits of two climate adaptation strategies for new RC structures placed in chloride-contaminated environments under various climate change scenarios. Their cost-effectiveness is measured in terms of the benefit-to-cost ratio (BCR) and the probability that BCR exceeds unity - i.e., Pr(BCR. > 1). It was found that increasing concrete strength grade is more cost-effective than increasing design cover. The results also indicate that the cost-effectiveness of a given adaptation strategy depends mainly on the type of structural component, exposure conditions and climate change scenarios.

Mortar joint thickness has a significant effect on capacity of structural masonry. Data on mortar joint thickness (bed and head joints) were collected from twelve typical storey-high walls at three different building sites and from four walls built in a research laboratory in Switzerland. The data obtained allowed an analysis of the spatial distribution of the joint thickness in each wall and the characterization of the probability distribution of joint thickness. The data has been statistically analysed and the results discussed: the central and dispersion measures were calculated and several probability distributions have been fitted to the sample data and subsequently tested using standard methods of statistical theory. Further, the results obtained from all four building sites have been compared, thus providing quantitative information about the quality of the work on different sites. The presented probabilistic information is then used to define reliability-based limit state specifications where the joint thickness acts as an important random variable. The reliability of the structural masonry subjected to a concentric normal force found that probabilistic modelling of bed joint thickness results in higher reliability indices.

2015Shi Y, Stewart MG, 'Spatial reliability analysis of explosive blast load damage to reinforced concrete columns', Structural Safety, 53 13-25 (2015)

Columns are the key load-bearing elements in frame structures and exterior columns are probably the most vulnerable structural components to terrorist attack. In this paper, a spatial reliability analysis is conducted to predict the damage for reinforced concrete (RC) columns subject to explosive blast loading. The spatial variability of material and dimensional properties of RC columns are modelled by stationary and non-stationary random fields. The variability of blast loading is also taken into consideration. Monte Carlo simulation and numerical methods are used to derive Blast Reliability Curves for RC columns under explosive loading for a number of terrorism threat scenarios, based on a high-fidelity physics-based computer programme LS-DYNA to estimate design and residual axial load-carrying capacity of RC columns. It was found that spatial variability has a significant effect on structural reliabilities and the spatial model will lead to more accurate predictions of damage and safety risks.

2015Stewart MG, 'Risk and economic viability of housing climate adaptation strategies for wind hazards in southeast Australia', Mitigation and Adaptation Strategies for Global Change, 20 601-622 (2015)

A changing climate and higher wind speeds means that residential construction is likely to receive more damage in the future if design standards are maintained at the current level. The vulnerability of residential construction may be reduced by an adaptation strategy that increases design wind speeds specified by Australian standards. The paper applies break-even analysis to compare the risks, costs and benefits of climate adaptation strategies for new housing in the three largest cities in Australia: Brisbane, Sydney and Melbourne. These cities are located in southeast Australia where wind hazard is dominated by synoptic winds (thunderstorms and east-coast lows). Break-even estimates of risk reduction and adaptation cost for designing new housing to enhanced standards were calculated for three synoptic wind pattern scenarios to 2070: (1) no change, (2) B1 and (3) A1FI emission scenarios. If the actual cost of adaptation exceeds the predicted break-even value, then adaptation is not cost-effective. It was found that this adaptation strategy can lead to risk reductions of 50¿80¿% at a cost of approximately 1¿% of house replacement value. If risk reduction is over 50¿%, discount rate is 4¿%, and there is no change of climate, the break-even analysis shows that adaptation is cost-effective for Sydney if the adaptation cost is less than 5¿9¿% of house replacement cost. Designing new housing to enhance wind classifications is also likely to be a cost-effective adaptation strategy for Brisbane and Melbourne.

2015Bastidas-Arteaga E, Stewart MG, 'Economic assessment of climate adaptation strategies for existing reinforced concrete structures subjected to chloride-induced corrosion', Structure and Infrastructure Engineering, (2015)

Reinforced concrete (RC) structures placed in chloride-contaminated environments are subjected to deterioration processes that affect their performance, serviceability and safety. Chloride ingress leads to corrosion initiation and its interaction with service loading could reduce its operational life. Chloride ingress and corrosion propagation are highly influenced by weather conditions in the surrounding environment including climate change. Therefore, both structural design and maintenance should be adapted to these new environmental conditions. This study focuses on the assessment of the costs and benefits of climate adaptation strategies for existing RC structures subjected to chloride ingress and climate change. We studied RC structures built at different periods under different construction standards in France. The cost-effectiveness of adaptation measures was measured in terms of the benefit-to-cost ratio (BCR) and the probability that BCR exceeds unity ¿ i.e. Pr(BCR>1). The results of the paper could provide practical advice to policy-makers to improve the management of existing RC structures under a changing climate by discussing the influence of the following factors on the mean BCR and Pr(BCR>1): specific exposure conditions, climate change scenarios, risk reduction due to the implementation of adaptation strategies, type of structural component, years of construction and adaptation, discount rates and damage costs.

2014Mueller J, Stewart MG, 'Evaluating counterterrorism spending', Journal of Economic Perspectives, 28 237-248 (2014) [C1]

In this article, we present a simple back-of-the-envelope approach for evaluating whether counterterrorism security measures reduce risk sufficiently to justify their costs. The approach uses only four variables: the consequences of a successful attack, the likelihood of a successful attack, the degree to which the security measure reduces risk, and the cost of the security measure. After measuring the cost of a counterterrorism measure, we explore a range of outcomes for the costs of terrorist attacks and a range of possible estimates for how much risk might be reduced by the measure. Then working from this mix of information and assumptions, we can calculate how many terrorist attacks (and of what size) would need to be averted to justify the cost of the counterterrorism measure in narrow cost-benefit terms. To illustrate this approach, we first apply it to the overall increases in domestic counterterrorism expenditures that have taken place since the terrorist attacks of September 11, 2001, and alternatively we apply it to just the FBI's counterterrorism efforts. We then evaluate evidence on the number and size of terrorist attacks that have actually been averted or might have been averted since 9/11.

2014Peng L, Stewart MG, 'Spatial time-dependent reliability analysis of corrosion damage to RC structures with climate change', Magazine of Concrete Research, 66 1154-1169 (2014) [C1]

The environment around concrete structures may be influenced by a changing climate, especially in the long run, leading to an acceleration of deterioration. Therefore, the safety, serviceability and durability of concrete infrastructure may decline at a faster rate than expected. Carbonation-induced deterioration to concrete structures constructed in Sydney, Australia and Kunming, China under a changing climate is investigated in this paper. Two emissions scenarios are considered - RCP 8.5 and RCP 4.5, representing high and medium greenhouse gas emissions scenarios respectively. The spatial time-dependent reliability analysis includes time-dependent climate scenarios and deterioration processes, as well as a large number of random variables and spatial random fields of material properties and dimensions. The surface of concrete structures is discretised into a large number of elements and the likelihood and extent of corrosion damage is calculated by tracking the evolution of the corrosion process of each element using Monte Carlo simulations. The results show that a changing climate could cause the extent of damage to increase by up to 6% for reinforced concrete infrastructure in Kunming. The findings may be used to assess climate adaptation measures in the design stage, as well as a cost-benefit analysis of climate adaptation measures.

2014Li J, Masia MJ, Stewart MG, Lawrence SJ, 'Spatial variability and stochastic strength prediction of unreinforced masonry walls in vertical bending', Engineering Structures, 59 787-797 (2014) [C1]

The flexural bond strength of unreinforced masonry (URM) is a key material property affecting wall out-of-plane lateral load capacity. It is well known that the unit flexural bond strength (defined here as the flexural strength of the bond between the brick and lower mortar bed joint associated with any given masonry unit (brick)) varies considerably between units, and that this spatial variability might significantly affect the structural performance and reliability of URM walls in flexure. The paper develops a computational method to predict the strength for non-load bearing single skin URM walls subject to one-way vertical bending considering unit-to-unit spatial variability of flexural bond strength. We characterise the probability distributions of wall strength and examine how spatial variability in unit flexural bond strength affects the variability of base cracking load, mid-height cracking load, peak load and behaviour of clay brick URM walls. This is done using 3-D non-linear Finite Element Analyses (FEA) and stochastic analysis in the form of Monte Carlo simulations. Varying COVs (0.1, 0.3 and 0.5) of unit flexural bond strength are considered. The mean and variance of wall strength are estimated to show the effect of spatial variability of flexural bond strength on wall strength. The failure modes of the wall are compared to show the significant differences between non-spatial and spatial analyses. © 2013.

Climate change may increase atmospheric CO2 concentration and temperature, change relative humidity (RH), and consequently change RC infrastructures' surrounding environment. Especially in the long run, the decline of the safety, serviceability and durability of RC structures may be accelerated. Carbonation induced corrosion damage of RC infrastructure in Xiamen and Shaoguan under a changing climate is investigated for time period 2010~2100. The projection of atmospheric CO2 concentration, temperature and RH in both cities are based on the representative concentration pathways (RCPs). The time-dependent reliability analysis was conducted by Monte Carlo simulation and includes the uncertainty of dimensions, material properties, climate projections, and predictive models. The corrosion damage risks of RC structures are represented by the probability of severe cracking of concrete cover. Results show that climate change may increase mean carbonation depth by 8 mm by 2100. Moreover, carbonation-induced damage risk for RC buildings in temperate areas can be increased by 12%~19%. This research provides a reference for impacts of future climate change on RC structures and development of climate adaptation strategies.

2014Mueller J, Stewart MG, 'Terrorism and counterterrorism in the US: the question of responsible policy-making', International Journal of Human Rights, 18 228-240 (2014) [C1]

Officials serving the public are tasked at the most fundamental level to spend funds in a manner that most effectively and efficiently keeps people safe. To do otherwise is irresponsible and, because human lives are at stake, immoral. In the case of counterterrorism policy-making, it is important to evaluate the degree to which any gains in security afforded by counterterrorism measures have been great enough to justify their cost. Risk analysis is an aid to responsible decision-making that does exactly that. We deal with four issues central to this approach, applying them to the hazard presented by terrorism: the cost per saved life, acceptable risk, cost-benefit analysis, and risk communication. We also assess the degree to which risk analysis has been coherently applied to counterterrorism efforts in the US in making or evaluating decisions that have cost taxpayers many hundreds of billions of dollars over the past dozen years. © 2014 Taylor & Francis.

2014Stewart MG, Wang X, Willgoose GR, 'Direct and indirect cost-and-benefit assessment of climate adaptation strategies for housing for extreme wind events in Queensland', Natural Hazards Review, 15 (2014) [C1]

The intensity of tropical cyclones and severe storms is likely to increase due to climate change. Brisbane and the northeast coast of Queensland are regions where design wind specifications may be inadequate under either current or likely future climate conditions. An appropriate adaptation strategy may be one that increases wind classifications for new houses, which leads to a reduced vulnerability of new construction. The present paper will assess the damage risks, adaptation costs, and cost-effectiveness of these adaptation measures for residential construction in Cairns, Townsville, Rockhampton, and South East Queensland, assuming time-dependent changes in the frequency and intensity of cyclonic and noncyclonic winds to 2100. Loss functions are also developed for direct and indirect losses. It was found that increasing design wind loads for new houses in Brisbane and South East Queensland will lead to a net benefit [net present value (NPV)] of up to $10.5 billion by 2100, assuming a discount rate of 4%, which includes approximately 95% of a direct benefit and 5% of an indirect benefit. The benefits are highest for Brisbane due to its large population and the high vulnerability of existing residential construction, and have a 90-100% likelihood of achieving a net benefit by 2100.

2014Peng L, Stewart MG, 'Climate change and corrosion damage risks for reinforced concrete infrastructure in China', Structure and Infrastructure Engineering, (2014)

A changing climate which leads to increases in atmospheric CO2 concentration, and changes in temperature and relative humidity (RH), especially in the longer term, will accelerate the deterioration processes and consequently decline the safety, serviceability and durability of reinforced concrete (RC) infrastructure. This paper presents an investigation of carbonation-induced deterioration in three typical Chinese cities (Kunming, Xiamen and Jinan) under a changing climate. The changing trends of atmospheric CO2, local temperature and RH of typical Chinese cities are projected based on the latest CO2 emission scenarios. The time-dependent analysis is based on Monte Carlo simulation, and includes the uncertainty of climate projections, deterioration processes, material properties, dimensions and accuracy of predictive models. Deterioration of RC structures is represented by the probabilities of reinforcement corrosion initiation and damage. It was found that the mean carbonation depths by 2100 may increase by up to 45% for RC structures in China due to a changing climate. It was also found that climate change can cause an additional 7-20% of carbonation-induced damage by 2100 for RC buildings in temperate or cold climate areas in China. The findings provide a basis for the development of climate adaptation strategies through the improved design of concrete structures. © 2014 © 2014 Taylor & Francis.

This paper presents a risk-based framework to assess the hurricane damage risks to distribution poles, and investigates the risks, costs and benefit of different mitigation strategies. It is estimated that power outages due to storms cause approximately $270 million in repair/replacement costs annually in the USA. Hurricane Irene alone left approximately 6 million residents without power along the east coast of the USA in 2011, causing an estimated $5-$7 billion in damages. These high repair/replacement costs warrant an investigation of mitigation strategies that may aid in reducing replacement and damage costs. This paper describes the reliability analysis of typical timber distribution poles and probabilistic wind models to determine failure probabilities for specific locations. Furthermore, in order to more accurately portray the behaviour of distribution poles, the proposed framework includes the degradation and service-proven reliability of timber distribution poles. Four mitigation strategies are developed, and the cost effectiveness of each strategy is evaluated. In order to assess the cost effectiveness, a life cycle cost analysis is conducted for each mitigation strategy. This paper finds that appropriate mitigation strategies can reduce replacement costs of distribution poles associated with hurricane wind by 2060. © 2013 © 2013 Taylor & Francis.

The paper will assess terrorist threats to new and existing bridges and the cost-effectiveness of protective counter-terrorism measures. This analysis will consider threat likelihood, cost of security measures, risk reduction and expected losses to compare the costs and benefits of protective measures to bridges to decide which protective measures are cost-effective. In this paper, a break-even cost-benefit analysis determines the minimum probability of an attack, absent the protective measures, that is required for the benefit of the protective measures to equal their cost for new and existing bridges. It was found that unless terrorist threat probabilities are high, then typical protective measures are not cost-effective. Bridges and other critical infrastructure are subject to a range of natural and man-made hazards, and terrorism is most likely not as important a threat as natural hazards. It was found that economic risks to bridges from floods, earthquakes, and ship impact are higher than threats from terrorism.

This paper presents a framework to assess the potential hurricane damage risks to residential construction. Studies show that hurricane wind, frequency and/or hurricane-induced surge may change as a result of climate change; therefore, hurricane risk assessments should be capable of accounting for the impacts climate change. The framework includes a hurricane wind field model, hurricane-induced surge height model and hurricane vulnerability models. Three case study locations (Miami-Dade County, FL; New Hanover County, NC and Galveston County, TX) are presented for two types of analyses: annual regional loss estimation and event-based regional loss estimation. Demographic information, such as median house value and changes in house numbers, and distribution of houses for different exposures, is used to estimate the time-dependent probability of damage with or without possible climate change-induced change in wind speed, frequency and/or surge height. Through both analyses, it was found that climate change may have a significant impact on regional hurricane damage losses.

2013Netherton MD, Stewart MG, 'What are some of the problems associated with the current methods of calculating explosive blast loads?', 10th International Conference on Shock and Impact Loads on Structures 2013, 65-74 (2013)

The most common methods for calculating explosive blast loads are deterministic; in that, the output will always be the same for given model-inputs. However, a statistical analysis of actual explosive blast loading field (test) data reveals a high level of variability of peak reflected pressure, impulse and time of positive phase duration from repeated tests where variability would be expected to be a minimum. Given that blast-loads from similar events are highly variable, and that the most common blast-load models do not account for such circumstances, the question we should now be asking is this: How can we improve our methods for predicting blast loads, such that (known) variability and uncertainty is appropriately considered, to ensure that we continue to give useful, usable and robust information to decision makers? In other words: What exactly is the best available method for giving your Boss advice on the risks associated with explosive blast loads? This paper explores the deterministic nature of commonly used blast-load models and discusses their limitations with respect to matters such as: explosive safety distances, the design loads on protective structures and the military's deliberate use of munitions. We argue that deterministic models do not adequately account for society's usual acceptance (or rejection) of the risks associated with damage and/or injury. A new probabilistically based blast-load model is developed which does take into account the observed (and very real) variability of explosive blast loads. Following which, new forms of risk-based advice are presented. This new probabilistic blast-load model uses statistical and probabilistic information taken from the literature as well as from our own explosive trials. Explosive scenarios of future interest could be from blast-loads resulting from (possible) terrorist activity, or, from current in-service military munitions. In either case, we argue that these new forms of risk-based advice (eg: the most probable blast-load or cost-effective mitigation) provides additional - and unique - utility for decision makers involved in the production, storage and operational use of explosives. The paper concludes with a discussion on how the new probabilistic blast-loading model can improve a decision maker's confidence with respect to explosive safety distances, magazine design, protective structures design, weaponeering and collateral damage estimation.

Quantified Risk Assessment (QRA) has been in wide use in risk management since the 1960s for systems ranging from aviation, nuclear power, and offshore platforms to medical treatment and pharmaceuticals. The Quantified Tree Risk Assessment (QTRA) system is examined considering the principles of QRA. A case study of 14 fig trees in Newcastle, Australia, illustrates some limitations of the QTRA process, and extrapolating risks for a single tree to a group of trees. There is a need for any risk management process involving trees, not only to assess the risk, but to weigh the benefits provided by trees by a risk-based cost-benefit analysis. Tree risk assessors should rely on benchmarks to ensure that their assessment is not outside of the realms of reality or scientific rigor. © 2013 International Society of Arboriculture.

Reliability-based safety assessment is used frequently in Europe and elsewhere to assess the need for maintenance and the remaining service life of structures. In order to assess the effect of corrosion, quantitatively, an experimental study was conducted using an accelerated corrosion testing technique. Vibration tests were carried out fortnightly to study its effect on the natural frequency of RC beams subject to corrosion. One beam was taken out and broken every four weeks. The mass losses of steel rebar were measured to determine the corrosion state. The experimental results are used to develop an empirical model that describes the relationship between natural frequency and corrosion loss. The statistics for model error for this relationship were then inferred. A spatial timedependent structural reliability analysis was developed to update the deterioration process and evaluate the probability of structural failure based on vibration results. The performance of RC beams is used to illustrate the reliability analysis developed in this paper. The inspection finding considered herein is the timing of test and the vibration results, which are used to provide an updated estimate of structural reliability. It was found that vibration test findings change, the future reliability predictions significantly. A description of structural reliability and reliability-based safety assessment is also provided, where failure probabilities are compared with a typical target failure probability to illustrate how condition assessment findings can be used to more accurately assess and often increase service life predictions. © 2011 Nova Science Publishers, Inc.

In Australia, typical design load combinations for serviceability are ¿

sQ and G + ¿

sQ (D and D + L in the US) where G and Q are design dead and live loads, respectively, and ¿

s is a short-term live load factor. Code calibration is conducted herein for Australian and US serviceability load combinations, for structural steel beams in flexure. The effects that office, retail, domestic and car parking loads and tributary areas have on serviceability reliability is described. It was found that serviceability reliabilities for different floor uses vary considerably for Australian and US serviceability load combinations; whereas the differences between serviceability reliabilities for one year and duration of a single tenancy reference periods were not great. Short-term live load factors for most floor uses were adjusted (sometimes significantly) to ensure that serviceability reliabilities exceed the minimum target level of 1.65. Consequently, the present paper provides suggested values for short-term live load factors that may be used in Australian and possibly in US codes. Copyright © 1996 Elsevier Science Ltd.

Available statistical data suggest that human error in design causes a significant proportion of performance failures; namely, structural failure, cost overruns, and delays. A Human Reliability Analysis (HRA) model has been developed to simulate the effect of human error on the design computations of a reinforced concrete beam. The proposed HRA model incorporates the effect of "self-corrections"; this is a process where tasks are re-evaluated if the result appears to be not within "reasonable" expectations. Calculation, table look-up, chart look-up, and table ranking microtasks were incorporated into the proposed HRA model; human perormance data are described for each of these microtasks. It was found that human error, particularly multiple errors, lead to a significant loss of structural safety. © 1992 Springer-Verlag New York Inc.

The 'human dimension' is the unpredictable nature of human behaviour. In structural engineering tasks it can be shown that human errors result from this behaviour, for the incidence of design error is a major cause of structural failure. A Probabilistic Risk Analysis (PRA) model has been developed to simulate the effects of human error on a typical design task. The design task considered is the design of a flexural member. A computer simulation technique and event-tree methods were employed. This model provides the basis for an investigation into the efficiency of two quality management measure; namely, (i) design checking and (ii) the use of safe load tables as a design aid. Comparisons between the efficiency of design checking and the use of safe load tables will be made. It is indicated that a designer using safe load tables (or similar design aids) will be more 'cost-effective' and less prone to error than designers not using such design aids.

Reviews of statistical surveys of structural failures indicate that human error is a major cause of failure. These surveys show that human error may occur in the planning, design, construction, or utilisation of a structure. However, the available data suggest that design error causes a significant proportion of structural failures. An investigation of the efficiency of a quality control measure (e.g., design checking) is reported which includes design checking guidelines for the structural engineering profession. The use of safe load tables (for steel member design) as a quality assurance measure is also investigated. It is indicated that a designer using safe load tables (or similar design aids) will be more 'cost effective' and less prone to error than designers not using such design aids. Comparisons between the efficiency of design checking and the use of safe load tables will be made.

On 28 December, 1989 the city of Newcastle was struck by a magnitude 5.6 earthquake killing 12 people and causing losses estimated at $1000 million. It was the first time a major Australian city has been so extensively damaged as a result of an earthquake, and the first time that deaths have occurred. With a few exceptions, most of the damage was to older loadbearing masonry construction or to infill masonry in modern framed construction. There was relatively little structural damage to modern buildings, industrial facilities and lifelines. This paper reviews the damage to structures and brings out the main points to be considered in future design and construction.

The process of structural design has received very little attention from the research community despite its centralness in day-to-day structural engineering. Much of the research which has been done has been carried out in Australia over a number of years and with the co-operation of many structural engineers. The present paper reviews the reasons for being engaged in this relatively unusual research activity and provides an overview of the work to date. A review is given of the incidence and type of errors made in basic design tasks such as calculations, table look-up and table interpolation, and how these errors relate to results obtained for more comprehensive tasks such as loading determination and member design. One of the outcomes of the work has been to suggest areas in certain current design codes which are prone to misinterpretation by practitioners. Preliminary results related to design computation checking and inspection are also reviewed. This work potentially has major implications for quality assurance programmes.

Overview checking occurs whenever an engineering design is reviewed by another engineer without specifically carrying out checking calculations or following through the design process in detail. Results are reported herein of a survey examining the effectiveness of overview checking. The respondents were requested to assess whether a structural design should be considered "undersized", "correct" or "oversized". Using the responses as a basis, a decision model is proposed for the effectiveness of overview checking as a function of error magnitude and of checker's experience. It is concluded that correct assessment of a design as "safe" is not a function of experience. However, it appears that more experience is beneficial in selecting economical designs. © 1989.

The paper will assess terrorist threats to bridge infrastructure and the cost-effectiveness of protective and counter-terrorism measures. This analysis will consider threat likelihood, cost of security measures, risk reduction and expected losses to compare the costs and benefits of protective measures to bridges to decide which protective measures are cost-effective. In this paper, a break-even cost-benefit analysis determines the minimum probability of a successful attack, absent the protective measures, that is required for the benefit of the protective measures to equal their cost. It was found that unless terrorist threat probabilities are high, then typical protective measures are not cost-effective. Bridges and other critical infrastructure are subject to a range of natural and man-made hazards, and terrorism is most likely not as important a threat as natural hazards. Economic risks due to terrorism are then compared with risks from flood and seismic hazards. It was found that economic risks to bridges from floods, earthquakes, and ship impact are significantly higher than threats from terrorism. © 2014 Taylor & Francis Group.

2013Stewart MG, Grant M, 'Reliability and blast load efficiency of improvised explosive devices', 10th International Conference on Shock and Impact Loads on Structures 2013 (2013) [E1]

Modelling of structural damage caused by explosive blast loads first requires knowledge of the characteristics of the blast load. Most vulnerability assessments assume that an IED will reach maximum TNT equivalency, and that the IED will successfully detonate. These assumptions will tend to over-estimate actual blast load effects. The paper develops an IED Probabilistic Risk Assessment model using a systems model for IED attacks based on IED device reliability and characterising the human aspects of IED attack operational effectiveness from existing databases of terrorist incidents. It was found that it the risk of loss (fatalities, property damage) is influenced more by the operational aspects of an attack (such as target selection, IED placement and attack timing) than the technical aspects of the device (i.e., design and manufacture).

Reinforced concrete (RC) structures deteriorate with time and corrosion of reinforcing steel is one of the main causes for that. In the paper a framework for reliability-based assessment of durability of RC concrete structures in corrosive environments will be briefly described. Existing models for corrosion initiation, corrosion-induced cracking, and effects of corrosion on stiffness and strength of RC members will be considered. Special attention will be paid to the effects of a changing climate on corrosion risks to RC structures.
