On analysis of energy dissipation performance of steel frame structure of buckling-restrained brace

The paper points out the energy dissipation brace is the important component in the steel structure and the reinforced concrete structure,indicates the buckling-restrained brace,as a new energy dissipation support,is researched at home and abroad and applied in projects increasingly,illustrates the analysis of the energy dissipation brace ability of the multi-layer steel frame is undertaken by SAP2000 finite element software.It is concluded that the buckling-restrained brace has better energy dissipation and shock absorption performance,so it is the new scheme for the structure anti-seismic design.
