A Discrete Element Approach for the Evaluation of the Seismic Response of Masonry Buildings

Abstract eng:
The evaluation of the seismic response of masonry buildings represents a relevant topic both in the field of the research and in the engineering practice. In the paper a discrete element approach for the evaluation of the seismic behaviour of masonry buildings is presented. The proposed methodology is based on a simple mechanical nonlinear scheme that, with a reduced computational cost with respect to a nonlinear finite element simulation, is able to predict both the in-plane and the out-of-plane nonlinear behavior of a masonry portion and, for assemblage, of a masonry building. The results appear to be suitable for the use of the proposed methodology in order to predict the nonlinear seismic response of masonry buildings by means of nonlinear static analyses.
