摘　　要：以多层混凝土框架为例,在框架中增设K型非对称摩擦耗能支撑。通过利用有限元软件SAP2000,对在罕遇地震作用下,角度不同的K型非对称耗能支撑与K型对称耗能支撑的时程分析,对其抗震性能进行分析研究和对比,得出在一定条件下,K型非对称摩擦耗能支撑可以取代K型对称摩擦耗能支撑的结论,使得平面布置更灵活,可供设计时参考使用。The multi-storey reinforced concrete frame structure whose frame has been added with a kind of unsymmetrical K-type friction energy dissipation brace is taken as an example in this article. The time history analysis of different angles of unsymmetrical K-type friction energy dissipation brace and symmetrical K-type friction energy dissipation brace under the rare earthquake has been done by using the finite element software SAP2000. The analysis and comparison on the seismic performance shows that symmetrical K-type friction energy dissipation brace can be replaced by unsymmetrical K-type friction energy dissipation brace under certain conditions. Plan layout could be more flexible by using the result which could become a reference to design.
