摘　　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。 The structural optimum design of torsion resistance for the complicated high-risc 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.
