This chapter provides an insight into the thermo-structural behaviour of
masonry walls at elevated temperatures, and the various parameters affecting
their structural response. A detailed description of the mechanical material
properties of various masonry materials at elevated temperatures is given. An
involved high temperature concrete material mathematical model is presented and
validated. The material model is implemented in a newly developed finite
element model, capable of simulating the thermo-structural behaviour of masonry
compartment walls subject to fire exposure on one side. The finite element model
was used to produce numerical examples which are compared with experimental
results.
