［摘要］提出了一种新型框架-核心筒耗能耦联结构，此结构将框架和核心筒分开，框架和核心筒之间通过水平向阻尼器连接。为了了解框架-核心筒耗能耦联结构在地震作用下的性能，采用SAP2000和PERFORM-3D有限元软件分别建立传统框架-核心筒结构、新型框架-核心筒耗能耦联结构有限元模型，对两种模型分别进行中震、大震弹性和大震弹塑性时程分析。结果表明：相比于传统框架-核心筒结构，新型框架-核心筒耗能耦联结构能有效耗散地震能量，降低楼层剪力，减小结构地震响应，表现出优异的抗震性能。

Abstract:A new frame-core tube energy dissipation coupling structure was proposed. The structure separates the frame and the core tube, and the frame and the core tube are connected by a horizontal damper. In order to understand the performance of the frame-core tube energy dissipation coupling structure under earthquake action, finite element software SAP2000 and PERFORM-3D were used to establish the traditional frame-core tube structure and the new frame-core tube energy dissipation coupling structure finite element model, elastic time-history analysis under fortification earthquake and rare earthquake, and elastoplastic time history analysis under rare earthquake were conducted for the two models. The results show that, compared with the traditional frame-core tube structure, the new frame-core tube energy dissipation coupling structure can effectively dissipate seismic energy, reduce the floor shear force, reduce the structural seismic response, and exhibit excellent seismic performance.

Keywords:frame-core tube energy coupling dissipation structure; damper; earthquake response; seismic performance
