| 摘 要： | 静力弹塑性分析（Push—over）是逐渐得到广泛应用的一种评估结构抗震性能的简化方法。型钢混凝土-钢筋混凝土混合结构（SRC—RC）由于其承载能力高、刚度大、延性好及耗能少等优点，在地震区得到了广泛的应用。本文以SRC—RC结构为例，对遭遇罕见地震后可能出现的破坏状况进行了较为精确的Push—over分析，结果显示结构的最大层间弹塑性位移角为1／407，满足在罕遇地震下对薄弱层弹塑性变形的要求。

| Abstract: | The push-over analysis is a simplified method to evaluating structural anti-earthquake function which is gradually used widely.While the shaped-steel reinforced concrete-reinforced concrete(SRC-RC) structure is often used in the earthquake-stricken areas for its virtues,including high bearing capacity,strong stiffness,excellent ductility and less energy consumption.With mathod of the push-over analysis,this research concisely analyzed the damage to the SRC-RC structure that might occur after the strong earthquake.The results show that the maximum elastic-plastic story-drift-angle of the SRC-RC structure is 1/407,which meets the requirement for elastic-plastic deformation of the weak storey under a rare earthquake. |
