［摘要］对高层建筑结构楼层侧向刚度的计算方法进行讨论，结合工程实例，采用几种现行不同计算方法进行楼层侧向刚度和楼层侧向刚度比对比分析。计算结果表明，对于复杂高层建筑结构，文献[3]的楼层侧向刚度计算方法能较好地反映层高突变、竖向构件截面变化、环桁架层和伸臂层对楼层侧向刚度的影响，因而计算的楼层侧向刚度比能较为准确判断结构的软弱层，可供工程项目设计参考。

Abstract:The calculation method of the story lateral stiffness of the high-rise building structure was discussed. In combination with engineering examples, several current different calculation methods were used to compare and analyze the lateral stiffness and the lateral stiffness ratio of the stories. The calculation results show that for complex high-rise building structures, the story lateral stiffness calculation method in literature ［3］ can better reflect the impacts on the story lateral stiffness by sudden changes in floor height, vertical member section changes, ring truss stories and outrigger stories. Therefore, the calculated story lateral stiffness ratio can accurately determine the weak story of the structure, which can be used as a reference in the design of engineering projects.

Keywords:story lateral stiffness; story lateral stiffness ratio; high-rise building structure
