In the present study a new discrete-element approach for the evaluation of the seismic resistance of composite reinforced concrete-masonry structures is presented.

Abstract
In the present study a new discrete-element approach for the evaluation of the seismic resistance of composite reinforced concrete-masonry structures is presented. In the proposed model, unreinforced masonry panels are modelled by means of two-dimensional discrete-elements, conceived by the authors for modelling masonry structures, whereas the reinforced concrete elements are modelled by lumped plasticity elements interacting with the masonry panels through nonlinear interface elements. The procedure has been applied for the evaluation of the seismic resistance of confined mixed masonry and reinforced concrete building that has been considered as representative of a wide class of residential buildings designed according to the 1909 seismic code and built principally in the cities of Messina and Reggio Calabria after the destructive 1908 earthquake.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
