Pushover analysis of large scale unreinforced masonry structures by means of a fully 2D non-linear model

A simple 2D model for the evaluation of the seismic performance of large scale unreinforced masonry structures in-plane loaded is presented. The approach is fully two dimensional and allows performing pushover analyses on large scale structures without the reduction of the walls to an equivalent frame, competing with 1D codes. In the model, a macroscopic approach is used, where the so called disturbed state concept (DSC) with modified …
