Energy dissipation structures are widely used because of their superior anti-seismic performance. The buckling restrained brace has been applied to the seismic design of various buildings because of its good energy dissipation performance and easy installation. Taking the seismic design of a building as an example, the elastic and elastoplastic time history analysis of the structure was carried out to compare the seismic response of the structure with damping and non damping. The results show that the interlayer displacement of the structure is reduced and the seismic performance of the structure is greatly improved when the Buckling Restrained Braced is attached to the structure, thus demonstrating the feasibility of the Buckling Restrained Braced as the energy dissipation element.%消能减震结构因其优越的抗震性能而得以广泛的运用,其中防屈曲支撑由于其良好的耗能性能及便于安装等优点而被运用到各类建筑的减震设计中.本文以某教学楼的减震设计为例,对结构进行弹性与弹塑性时程分析,对比减震与非减震结构的地震响应.结果表明结构在附设了防屈曲支撑后,减小了结构的层间位移,较大程度的提高了结构的抗震性能,体现了防屈曲支撑作为消能减震元件的可行性.
