摘　　要：为研究型钢-混凝土混合结构的抗震性能,选用ETABS有限元软件,建立了一栋6层型钢-混凝土框架结构的数值分析模型。采用振型分解反应谱法和动力时程法,研究了罕遇与极罕遇状态下型钢混凝土结构的抗震稳定性。计算结果表明,型钢混凝土框架结构具有较好的抗震性能,层剪力逐层减小,层位移逐层增大,层间位移角均小于1/50rad。对型钢混凝土框架分析结果表明,只要按照抗规限制罕遇和极罕遇地震时结构弹塑性层间位移角,即可满足“大震不倒”的要求。In order to study the seismic performance of steel-concrete hybrid structure.The numerical analysis model of a six-storey steel-concrete frame structure was established by using ETABS finite element software.The seismic stability of steel-concrete structure under rare and extremely rare conditions was studied by using mode decomposition response spectrum method and dynamic time history method.The calculation results show that the steel reinforced concrete frame structure has good seismic performance.The shear force decreases layer by layer,the displacement increases layer by layer,and the displacement angle between layers is less than 1/50.The analysis result of steel reinforced concrete frame shows that as long as the elastic-plastic inter-storey displacement angle of the structure is limited according to the rules,it can meet the requirement of“not falling down in violent earthquakes”.
