The Damping Energy Dissipation Study on Buckling Restrained Brace in Multilayer Steel Frame

Abstract:

The buckling-restrained brace has stable energy dissipation capability. It has been widely used in recent years. This paper uses finite element software ANSYS to do non-linear time history analysis for Center Braced Steel Frame, Eccentrically Braced Steel Frame, Buckling-restrained Braced Steel Frame under the earthquake. The results show that: (1) The peak acceleration, residual displacement and top floor displacement of buckling-restrained braced steel frame is smaller than the other two brace frames, provide support for the structure stability. (2) The damping energy and bracing energy dissipation capability of buckling-restrained braces and eccentrically braced are strong, so it can avoid the collapse of the main structure under the large or medium earthquake.
