摘　　要：以一个多层钢筋混凝土框架结构为对象,在框架中增设大倾斜角K型钢筋混凝土摩擦耗能支撑体系,并将其简化为简单的平面框架,运用SAP2000对不同的支撑刚度进行罕遇地震作用下的时程分析,研究大倾斜角情况下影响耗能器耗能能力的因素,提出在倾斜角很大的情况下提高耗能器耗能能力的方法,使安装K型摩擦耗能器的建筑物能更加灵活的进行建筑的平面布置。The multi-storey reinforced concrete frame structrue whose frame has been added with a big slope angle K-type friction energy dissipation brace is taken as an example in this article. And it is simplified to a simple plane frame. The time history analysis of big slope angle different rigidity of K-type friction energy dissipation brace under the rare earthquake has been done by using the finite element software SAP2000. In the big slope angle cases, the influencing factors of energy dissipator energy dissipation capacity is studied, Plan layout could be more flexible by using the result which could become a reference to design.
