Abstract

A non linear finite element model for the seismic analysis of an infilled frame is proposed. Two no-tension struts to simulate the interaction between the r.c. frame and the infill wall, including windows and door openings, are calibrated on numerical evaluations. Results show that two different reduction factors have to be applied to stiffness and strength in order to consider the effects of openings compared to the full infill panel. The role of light infill walls - even with openings - is proved to be important. Keywords: infilled r.c. frame, equivalent strut, seismic behaviour. 1 Introduction Most studies on infill wall behaviour aim
