摘要
某高层建筑为钢筋混凝土框架结构体系,为提高结构的抗震性能,增设了防屈曲支撑,为了验证防屈曲支撑的减震效果,对无支撑结构、普通钢支撑结构和附加防屈曲支撑结构进行了多遇地震和罕遇地震下的抗震性能分析。分析结果表明:增设防屈曲支撑后可有效改善结构的抗震性能,从而提高结构抵抗地震作用的能力。
A high-rise building belongs to a reinforced concrete structure,buckling restrained brace( BRB) is used to improve the seismic performance of the structure. In order to verify the damping effect of BRB,response spectrum analysis and time history analysis are performed for no brace structures,common steel brace structures and structures with BRB. The study indicates that seismic performance can be improved effectively by the addition of BRB to the structure,thereby enhancing its ability to resist seismic load.
