摘　　要：针对常用的高层钢框架 -支撑结构 ,考虑材料非线性和几何非线性 ,建立了框架部分、支撑部分的二阶动力分析模型。用等效线性方法对结构进行非线性随机地震响应分析 ,结合工程算例 ,论述不同场地土、不同层数、不同支撑情况下 。Related to the steel braced frame structures in highrise buildings, the dynamic analysis models of the frame element and the brace element are set up considering material nonlinerity and geometry nonlinerity. The nonlinear random seismic response analysis is carried out based on equivalent linearization technique. Numerical examples are given herein, and the second order effects on the statistic values of the structure are discussed under different site conditions and different storeys.
