摘　　要：为了研究设置金属阻尼器的框架结构的耗能减震效果,以某高烈度区超长框架结构为工程背景,通过有限元软件SAP2000分析了结构在罕遇地震作用下的抗震性能和减震效果。分析结构表明:设置金属阻尼器的某超长框架结构的抗震性能有了很大的提高,在罕遇地震作用下能够满足"大震不倒"的性能要求。In order to study the vibration reduction effect of the frame structure mounting metal damper, taking super-long frame structure as engineering background, this paper analyzes the seismic performance and vibration reduction effect of the structure under seldom occurred earthquake by use of the finite element software SAP2000. Results show that the seismic performance of the super-long frame structure mounting metal damper has a great improvement, it can meet the performance requirements of the ＂it will not collapse under severe earthquake＂.
