| 摘 要： | 超高层钢结构体系设计中，为提高结构的整体刚度，通常沿高度方向设置一道或多道水平加强层，而水平加强层的设置对其抗震性能有较大的影响。利用ANSYS有限元计算软件。分析了设置水平加强层后超高层钢框架-支撑结构地震响应。通过32层结构模型的6种不同设置加强层的方案比较，研究了加强层的数量对结构的侧向刚度、地震作用下构件内力以及内筒和外框架水平层剪力分配的影响。以68层的武汉国际证券大厦为例进行验证。用振型分解反应谱方法方法分析了常遇地震作用下的结构响应，对水平加强层的运用有借鉴价值。

| Abstract: | The Effect of horizontal strengthened story to the seismic response of super high - rise steel braced frame is analyzed in this paper through the finite element software ANSYS. By comparison of six different schemes of a 32 - story building, further research is presented on the influence of the quantity of strengthened story to the lateral stiffness, the inner force of components under earthquake and the distribution of shear force among inner tube and outer frame. According to the study, the Wuhan International Securities Mansion, which is a super high -rise steel structure, is described as verification. The response of the building is analyzed in small earthquake. The study can serve as the references of super high - rise structure with horizontal strengthened story design. |
