【提要】  通过广州中信君庭复杂高层建筑结构抗扭优化设计，详细论述了建筑方案设计所决定的结构方案选择、结构布置以及结构变形缝设置对复杂高层建筑结构抗扭设计的影响。工程计算分析表明，对平面近似正方形或长宽比不太大的长方形结构，当主要抗侧力结构布置严重偏心时，结构的平面扭转规则性很难满足规范要求；对于平面长宽比较大的近似矩形结构平面，在偶然偏心地震作用下，亦很难满足规范关于结构平面扭转规则性的要求；对于部分框支剪力墙结构，当转换层层高较大时，转换层以上结构抗侧刚度由最大层间位移角控制，转换层以下则由转换层与其上层楼层侧向刚度比控制。

Abstract:The structural optimum design of torsion resistance for the complicated highrise building of Zhongxin Junting in Guangzhou is introduced. The influencing factors of the structural torsion resistance behavior for complicated highrise buildings are discussed，such as the choice of the structural system determined by architecture，structural arrangement and the set of a structure movement joint. As indicated in the analysis of the project，the primary lateralforceresisting system of the structure，which has a squareapproximate plane or a small lengthwidth ratio，exhibits severe inherent torsion，and it"s very difficult to meet the structural torsionregular requirements of the current codes，so is the structure which has a rectangleapproximate plane with large lengthwidth ratio including accidental torsion. If the height of the transfer story for partial framesupported shear wall structures is larger，the lateral stiffness properties are determined by the maximum of storydrift ratio above the transfer story and by the storylateralstiffness ratio below the transfer story.
