摘　　要： 高层建筑设备层往往给结构设计带来刚度比不满足规范限值的问题。本文以某实际工程结构为研究对象,采用弹性分析方法,分析了两种设备层层高方案对设备层关键构件、结构位移、层间位移角等的影响程度及其相关性,并采用动力弹塑性分析方法对比分析了两种设备层结构方案在罕遇地震作用下的结构位移、层间位移角及破坏模式的差异,探讨了结构刚度比计算方法与分析结果的相关性,得到了一些设计有益的结论。 Typically the mechanical story causes the story stiffness ratio to be not satisfied with code requirements.Taking one real engineering structure and using elastic analysis,this paper investigates the influence and dependency of two mechanical story structure schemes with different story-heights on the key member,deformation and drift.The differences of the structure deformation,drift and damage pattern under rare earthquake for two schemes are compared by using dynamic elastoplastic analysis.The relationships between the story stiffness calculation method and the analysis results are also discussed and some helpful conclusions for the structure design are obtained.
