摘　　要：采用外包钢加固框架底层柱后,整体结构的质量、刚度、周期等发生了较大变化,应进行整体结构的地震反应分析。结合具体的工程实例,采用有限元程序SAP2000,对外包钢加固后某5层钢筋混凝土框架结构进行抗震性能的弹塑性分析,计算结果可为抗震设计提供参考。Significant differences occurred in the mass, stiffness and period after strengthening concrete column with exterior steel-enclosed at bottom layer. It is necessary to analyze the seismic behavior of the overall structure. In this paper, an FEA software package SAP2000 was employed to a five-storey wrapped steel concrete frame structure to do the dynamic analysis on the seismic properties. Some suggestions were proposed on aseismic strengthening design.
