Abstract

This paper presents a numerical study on seismic energy dissipation in a steel frame structure featuring buckling restrained braces (BRBs) for seismic protection. The Real-ESSI Simulator is used to construct a nonlinear finite element model of a twostory building that was designed by following ASCE-7 guidelines. The numerical model also features a spread foundation, underlying soil layers, and the soilfoundation interface. The model is excited by seismic motion that has two orthogonal components in the horizontal plane. Eigen analysis and dynamic time domain analysis are performed and discussed. The distribution and evolution of energy dissipation within the system is analysed. Of particular interest is the performance of the BRBs during a seismic event, in terms of their ability to dissipate seismic energy.
