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。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 capac- ity, 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.
