Modelling the nonlinear static response of a 2-storey URM benchmark case study: comparison among different modelling strategies using two- and three-dimensional elements

Abstract This paper aims at comparing the use of different software environments for study a simple unreinforced masonry building through nonlinear static analyses. The presented results are part wider research project conducted within ReLUIS consortium, and specifically task whose purpose is providing practitioners with tools an aware employment commercial packages modelling structures. In this one benchmark structures program analysed; two-story characterized by rigid horizontal diaphragms, considering configurations in terms openings arrangements effectiveness ring beams, subjected to seismic load conditions. Software two- three- dimensional structural models employed, obtained compared capacity curves collapse mechanisms. One critical aspects on basic assumptions made way apply loads further investigated. addition, role shear strength analysed correlating mechanical properties be adopted micro- macro- models. considered present very features, analogies differences critically interpreted view hypotheses strategies constitutive laws.
