Abstract

This paper presents a non-linear FEM analysis of reinforced concrete (RC) frames, with and without masonry infills, subjected to a column loss as a result of an extreme unforeseen event. The objective is to assess the importance of non-resistant masonry walls and their contribution to the overall resistance and stiffness of RC buildings, as well as understand the failure modes associated with eccentric loading. The present analysis was performed using the Atena3D, a software directed to model RC and masonry elements. A RC frame without masonry model served as reference followed by a RC frame with a double leaf traditional brick wall. The numerical models presented a faithful simulation of the experimental tests capturing the evolution of cracking and the correct failure modes.
