摘　　要：采用MIDAS有限元分析模型对型钢混凝土(SRC)构件的塑性铰进行了分析和确定,采用静力弹塑性分析方法对3跨5层框架在不同线刚度比的情况下进行了分析。结果表明,合理的梁柱线刚度比可使SRC柱-钢梁框架表现出更优越的抗震性能。The finite element method based on MIDAS finite element model to analyze and determinate the plastic hinge property of SRC members is adopted. Pushover analysis is performed on a hybrid frame of SRC column-steel beam with three bays and five stories based on different linear stiffness ratios of beam to column. The results demonstrate that hybrid frame of SRC column-steel beam which has reasonable linear stiffness ratio of beam to column has predominant earthquake-resistant behavior.
