［摘要］框架-双核心筒结构是适用于标准楼层平面为长形或异形的高层建筑的一种结构形式。讨论了此种结构设计对标准层平面为长形或异形的高层建筑的适用性和合理性，对其性能及影响因素进行了基于非线性纤维束杆系模型、细分网格非线性分层壳模型的动力弹塑性分析研究，并与框架-单核心筒结构进行了对比分析，最后提出了相应的结构设计建议。

Abstract:Frame-double corewall structure is a structure type which applies to the high-rise buildings with standard floor plane of long or irregular shape. The applicability and rationality of the design for high-rise buildings with standard floor plane of long or irregular shape was discussed. Dynamic elasto-plastic analysis and study were conducted on performance and influential factors of the structure based on with non-linear fibre bundle bar system model and non-linear layered shell model. And the analysis results were analyzed and compared with the frame-corewall structure. Corresponding structural design recommendations were proposed finally.

Keywords:frame-double corewall; earthquake response; floor stress; seismic performance; dynamic elasto-plastic  analysis
