［摘要］提出了一種新型框架-核心筒耗能耦聯(lián)結(jié)構(gòu)，此結(jié)構(gòu)將框架和核心筒分開(kāi)，框架和核心筒之間通過(guò)水平向阻尼器連接。為了了解框架-核心筒耗能耦聯(lián)結(jié)構(gòu)在地震作用下的性能，采用SAP2000和PERFORM-3D有限元軟件分別建立傳統(tǒng)框架-核心筒結(jié)構(gòu)、新型框架-核心筒耗能耦聯(lián)結(jié)構(gòu)有限元模型，對(duì)兩種模型分別進(jìn)行中震、大震彈性和大震彈塑性時(shí)程分析。結(jié)果表明：相比于傳統(tǒng)框架-核心筒結(jié)構(gòu)，新型框架-核心筒耗能耦聯(lián)結(jié)構(gòu)能有效耗散地震能量，降低樓層剪力，減小結(jié)構(gòu)地震響應(yīng)，表現(xiàn)出優(yōu)異的抗震性能。

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
