| 摘 要： | 根据《高层建筑混凝土结构技术规程》和《建筑抗震设计规范》对高位转换结构体系的框支层的层间位移和结构等效侧向刚度的限制要求，采用等效侧向刚度计算方法，将高位转换防屈曲支撑减震结构分解成框撑剪力墙结构和纯剪力墙结构，结合框支结构位移计算方法，推导出了高位转换防屈曲支撑减震结构支撑合理弹性刚度的计算公式及设计方法。通过算例分析得出，采用本文推导出的计算高位转换防屈曲支撑减震结构的支撑弹性刚度计算公式和设计方法是可行的，并且该计算公式简单实用，可用于高位转换防屈曲支撑减震结构中支撑的初步设计。

| Abstract: | Based on the limited demands of inter-story drift and equivalent lateral rigidity ratio of a high-level transfer story structure in the technical specification for concrete structures of tall building and the code for seismic design of buildings,a calculation model that a high-level transfer story structure with BRBs was decomposed into a frame-with-BRBs-shear-wall structure below its transfer story and a shear-wall structure above its transfer story with an equivalent lateral rigidity ratio was proposed.Th... |
