ABSTRACT
Unreinforced Masonry (URM) buildings make up a substantial proportion of existing building stock, and continue to pose large seismic risk in many parts of the world. In evaluating their seismic vulnerability, efficient numerical models are required, that are capable of simulating the inelastic building behaviour. The equivalent frame modelling procedure (Magenes & Della Fontana 1998) has been shown to be a promising practical approach capable of simulating the salient response mechanisms of URM buildings, without incurring the large computational penalty of finite element analysis.
