摘　　要：高层塔楼偏置结构在地震力的作用下,对结构平面内扭转进行分析,探寻结构在刚度分布变化和控制扭转的参数变化规律,分析结构平面内扭转应力集中区域,调整受扭构件和抗侧力构件的刚度是结构抗扭计算和抗扭控制上的关键点,通过增加构件在平面分布上的合理性和优化调整结构构件尺寸等,计算得出分析结果:应对结构受扭不利处的抗侧力构件进行优化,适当增加结构的构造措施来增强结构刚度和结构抗扭能力,同时优化布置抗侧力力构件的位置。High-rise tower offset structure under the action of earthquake force, analyze the structure plane change, explore structure on the distri- bution of the stiffness change and control the parameters of the reverse change law of in-plane torsional stress concentrated area, analysis of struc- ture adjustment of the torsional component and component to resist lateral force of the torsional stiffness is the structure calculation and torsional control on key points, by increasing the rationality of the component on the planar distribution and optimization of adjusting structural scantlings, calculated results： twisting the disadvantage in response to the structure of component to resist lateral force optimization, proper increase of the structure of the construction measures to enhance structural stiffness and torsional ability, at the same time, the position of the lateral force resis- tance of optimal placement of the component.
