［摘要］对当前超高层建筑伸臂加强层结构设计的一些问题进行了讨论，指出了加强层位置和数量对超高层建筑的顶点位移、基本周期、顶部风振加速度、层间位移角、框架倾覆力矩、墙体拉力等的影响。经分析给出了结合控制目标设置加强层位置和数量的选择方法，对顶部设置加强层进行讨论，结果表明顶部加强层并非较优选择，同时提出了伸臂桁架构件截面的设定方法，结合工程实例说明该方法的应用。

Abstract:Some issues in the structural design of the outrigger strengthening layer in super high-rise buildings were discussed. The influences of the quantity and location of strengthening layers of super high-rise buildings on top displacement, basic period, top wind-induced acceleration, inter-layer displacement angle, frame overturning moment and wall tension were studied. Based on the analysis, the arrangement method of the location and quantity of the strengthening layer was presented based on control goal, and the setting of the strengthening layer on the top of the super high-rise buildings was discussed. The results show that the top strengthening layer is not an optimal choice, and the setting method for cross-section of outrigger component was put forward. The application of this method was illustrated combined with practical engineering.

Keywords:outrigger strengthening layer; structural control goal; quantity and location; top strengthening layer; cross-section of outrigger component
