| 摘 要： | 为研究轴压比和套箍系数对钢管混凝土框架地震反应的影响,建立了钢管混凝土框架结构有限元分析模型,将该模型的计算结果与钢管混凝土框架结构振动台试验结果进行对比,两者符合较好.利用此模型,输入EL-centro地震波和天津地震波(N-S),对不同轴压比和套箍系数的钢管混凝土框架结构地震反应进行了有限元分析,并着重对比了结构位移反应.结果表明:轴压比提高使结构层间位移角值增大,套箍系数增大使结构层间位移角值减小.

| Abstract: | In order to research the effect of axial compression ratio and confining parameter on sismic response of CFST frame,its finite element analysis model is built.The calculational result is compared with the experimental under shaking table test,and they agree with each other,so this model can be applied to dynamical analysis of CFST frame.According to this model with El-Centro earthquake wave and Tianjin earthquake wave,finite element analysis on seismic response of CFST under different axial compression ratio and confining parameter is carried out with the comparison of the displacement responses of the structure.The results show that the drift angle between stories of CFST frames increases with the increasing of the axial compression ratio and the drift angle between stories of CFST frames decreases with the increasing of the confining parameter. |
