Earthquake Protection of Masonry Buildings Using Fibre Reinforced Polymer Strengthening
Unreinforced masonry construction is vulnerable to damage during earthquake loading as a result of its high mass and relatively low tensile strength and ductility. Much of the built infrastructure in Australia and other parts of the world uses unreinforced masonry construction.
The overall aim of this project is to develop new methods for earthquake protection of brick masonry buildings using fibre reinforced polymer (FRP) strips and other forms of reinforcement which can be applied (retrofitted) to existing construction. The methods developed in this project will be able to be applied so that the aesthetic appearance of the masonry construction is not destroyed while still providing the additional strength and ductility needed to safely withstand earthquake shaking.
In order to accomplish this, the fundamental bond-slip behaviour between reinforcement and brickwork under cyclic loading must first be fully understood and quantified. Design methodology based on this cyclic bond behaviour will be validated with full scale tests on actual buildings.
The project involves collaboration between researchers at The University of Newcastle, The University of Adelaide and Auckland University. In addition to the investigators named above, The project involves numerous RHD students and postdoctoral researchers.
