Abstract

A number of simplified methodologies have been proposed aiming at preparing numerical tools
suitable for engineering application, to predict the nonlinear seismic behavior of infilled frame structures.
In this paper, a 2D discrete macro element model (DMEM) for the simulation of the in-plane behavior of
RC frames with infill walls, is presented, validated with an experimental result that investigate the
influence of infill masonry, and evaluated with a proposed Finite Element model (FEM). In this model, the
frame members are modeled by beam-column elements with lumped plasticity, while the infills
contribution are modeled by plane discrete-element. As an extended study, a 2D prototype of multistory
frame building, for which the results of pseudo dynamic tests are available, is investigated. The ability of
the considered DMEM to predict the in-plane behavior of infill masonry elements is investigated, the
merits and drawbacks are highlighted.
