摘　　要：为了研究铅阻尼器在超高层结构中的耗能减震效果,采用非线性分析软件PERFORM-3D对超高层结构进行了罕遇地震作用下的有限元分析,对比了不同地震波作用下的结构弹塑性分析结果。分析结果表明:设置铅阻尼器的超高层建筑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。研究为铅阻尼器在超高层结构中的应用提供了成功的工程案例,其设计思路可以为超高层结构的减震控制提供有益的借鉴和参考。To study seismic reduction effect of lead dampers in the Superhigh-rise structure, tis paper conducts non- linear finite element analysis by use of software PERFORM-3D to research the seismic performance of a superhigh- rise frame - shear wall structure with lead dampers under the action of the rare earthquake and compares the analy- sis results of the structure under the action of different seismic waves in this paper. The results show that the struc- tural seismic performance improves significantly, the demand of ＂no collapse in strong earthquake＂ can be satis- fied ; a successful engineering case is provided for the application of lead dampers in the seismic reduction design of superhigh - rise frame - shear wall structure ; and the proposed design thinking may give a reference to seismic re- sponse reduction and control of superhigh-rise structure
