The Buckling-Restrained Braces is an excellent seismic energy dissipator. In this paper, the effects of the three core width-thickness ratios, gaps, and constraint ratios of the Buckling-Restrained Braces on the seismic performance of the Buckling-Restrained Braces are studied and modeled and analyzed by ABAQUS The simulation results show that the Buckling-Restrained Braces has the best seismic performance when the width-to-thickness ratio is 10-16; when the gap is 1-2mm, the Buckling-Restrained Braces has the best seismic performance; when the constraint ratio is about 5, the Buckling-Restrained Braces The best seismic performance.
