Project Description

In order to design or numerically simulate the behaviour of unreinforced masonry structures it is necessary to obtain detailed information about the material behaviour at the micro and macro level. This means that it is necessary to understand the behaviour of the masonry units, the mortar joints and the unit/mortar interface under tension, compression, bending and shear.

Furthermore, it is necessary to have information about the full range of behaviour from linear elastic, through cracking and softening to post softening behaviour. This project represents a collection of work over several years which has implemented existing, and developed new, carefully controlled experiments to accurately measure masonry material behaviour.

The project includes investigations of masonry behaviour under direct tension and direct compression, the flexural behaviour of masonry in vertical bending, horizontal bending and two way bending, the shear behaviour of mortar joints, and the behaviour of wall ties in cavity and veneer construction.
