摘要：According to the mechanical performance and energy dissipation characteristics of buckling restrained brace, combined with the seismic design idea of code for seismic design of buildings(GB 50011 -2010), we put forward the displacement-based design method for structures with buckling restrained brace. In this paper, we analyze the seismic design of high-rise buildings and test the relationship between structural target displacement and BRB added stiffness for a single-degree-reedom system. By using an engineering example to verify the validity of the design method, the time history analysis results to elastic and elastic-plastic show that the displacement of BRB frame structure under frequent earthquake can reach the expected target displacement, under rare earthquake, the input energy are dissipated by BRB, improving the seismic capacity and safety reserves
