［摘要］框架-雙核心筒結(jié)構(gòu)是適用于標(biāo)準(zhǔn)樓層平面為長(zhǎng)形或異形的高層建筑的一種結(jié)構(gòu)形式。討論了此種結(jié)構(gòu)設(shè)計(jì)對(duì)標(biāo)準(zhǔn)層平面為長(zhǎng)形或異形的高層建筑的適用性和合理性，對(duì)其性能及影響因素進(jìn)行了基于非線性纖維束桿系模型、細(xì)分網(wǎng)格非線性分層殼模型的動(dòng)力彈塑性分析研究，并與框架-單核心筒結(jié)構(gòu)進(jìn)行了對(duì)比分析，最后提出了相應(yīng)的結(jié)構(gòu)設(shè)計(jì)建議。

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
