A mechanical macro-element model representative of the in-plane non-linear behaviour of masonry piers and lintels (with shear-sliding, bending-rocking damage mechanisms and compressive crushing) has been used to realize models of masonry walls and whole three-dimensional buildings. Both for two - and three-dimensional models, several structural analysis procedures have been implemented: non-linear incremental, pushover, modal and non-linear dynamic. The numerical simulation of an interesting quasi-static experimental test on a full scale masonry building specimen has been used as significant validation of the model implemented in the TREMURI code. Pushover analysis permits to obtain the capacity curve of the 3-dimensional building and this result can also be used in the Capacity Spectrum Method implementation for URM buildings.

Abstract
A mechanical macro-element model representative of the in-plane non-linear behaviour of masonry piers and lintels (with shear-sliding, bending-rocking damage mechanisms and compressive crushing) has been used to realize models of masonry walls and whole three-dimensional buildings. Both for two - and three-dimensional models, several structural analysis procedures have been implemented: non-linear incremental, pushover, modal and non-linear dynamic. The numerical simulation of an interesting quasi-static experimental test on a full scale masonry building specimen has been used as significant validation of the model implemented in the TREMURI code. Pushover analysis permits to obtain the capacity curve of the 3-dimensional building and this result can also be used in the Capacity Spectrum Method implementation for URM buildings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
