【摘要】 基于大型通用有限元分析软件ANSYS,针对洪家渡水电站厂房钢—混凝土叠合排架柱,建立了矩形钢管混凝土柱三维动力有限元计算模型.对钢管混凝土叠合柱进行了模态分析和共振校核,并运用反应谱法计算了叠合柱沿横截面的长度方向和厚度方向水平地震时的地震反应.计算成果合理,符合工程实际,为工程设计提供了科学的参考依据.更多还原

【Abstract】 Based on ANSYS,a well-known large general finite element method analysis software, a 3-D dynamic finite element model of rectangular concrete filled steel tube column was built to simulation a steel concrete bent column in the powerhouse of Hongjiadu hydropower station.On the basis of this concrete filled steel tube composite column model modal analysis and resonance check were achieved,and response spectrum method was used to calculate the seismic response of the composite column under the horizontal earthquake along the length direction and the thickness direction of the transverse section.The result is reasonable and in agreement with the engineering practice, and provides scientific reference base for engineering design.更多还原
