摘　　要：隅撑的布置角度、长度及隅撑支撑的截面刚度对结构的抗侧刚度有着重要影响。不同的隅撑布置角度、长度及隅撑支撑截面刚度,结构的抗震性能往往会有很大差异。本文通过改变隅撑支撑参数,研究分析罕遇地震作用下隅撑支撑参数对钢结构加层抗震性能的影响。The layout angle, section stiffness ,length of the knee brace have an important impact on the stiffness of the structure. The seismic performance of the structure varies with the above elements. In this paper,the impact of parameters of the knee brace on the seismic performances of steel story - adding structure were studied under rare earthquakes through changing parameters.

关 键 词：钢结构加层 隅撑支撑 抗震性能
