| 摘 要： | 为了研究方钢管混凝土结构的抗震性能，基于一榀三层两跨方钢管混凝土框架的拟静力试验，分析了反复水平荷载作用下框架的滞回曲线，并根据滞回曲线进一步得出了框架顶层骨架曲线及相应的恢复力模型，研究了钢管混凝土框架的延性、强度与刚度的退化等性能．采用非线性有限元分析方法，将恢复力模型应用到混凝土弹性模量退化方程中，并对试验结果进行了计算模拟．结果证明，理论分析结果与试验结果吻合较好．

| Abstract: | In order to study the seismic behavior of concrete-filled rectangular tubular structure,the hysteretic curve under cyclic loading is analyzed based on a quasi-static test of a two-span, three-storey concrete-filled rectangular steel tubular frame (CRSTF). According to the hysteretic curve, the top layer framework curve and the corresponding resilience model are obtained. The ductility characteristics, stiffness and strength degeneration are studied. By using nonlinear finite element method, theoretical analysis in which the resilience model is applied into the degeneration equation of concrete elastic module is carried out, and the test results are simulated. The results show that a good agreement is reached between the theoretical predictions and available experimental results. |
