ABSTRACT
An accurate estimation of the dissipative capacity and of the cyclic behaviour under seismic actions are in general necessary. The most computationally convenient way to model regular and simple masonry buildings is offered from the Equivalent Frame Method, in which piers and spandrels are schematized with beam-type element, and the nodal regions are supposed fully rigid. The model has been validated comparing experimental and numerical results on single walls and on an entire building available in literature. It is shown that the developed macroelement is able to adapt the resulting cyclic law on the base of the slenderness and the compressive load of the wall. Two masonry facades taken from literature were analysed. The cyclic behaviour of the first one, tested experimentally, was reproduced with a static analysis, finding a good fitness with experimental results. An Incremental Dynamic Analysis was performed on the second one, with the aim to validate the dynamic behaviour of the proposed macroelement.
