大跨度钢结构厂房三维有限元动力分析

Three-dimensional Dynamic Finite Element Analysis of Large-span Steel-structural Factory Building

采用大型通用有限元程序ANSYS建立了某水电站钢结构厂房的三维有限元模型,进行了钢结构厂房的整体三维有限元动力分析,动力分析采用时程分析法并考虑峰值加速度0.1g进行分析;最终得到了钢结构厂房的地震动力响应,并对结构安全性进行了校核。其计算成果对类似工程设计与施工具有直接指导和参考意义。

The whole 3-D finite element model of a large-span steel-structural factory building was established by using the program ANSYS,then the three-dimensional dynamic finite element analysis was made,in which the peak value of accelerated speed was used to 0.1 g.And finally the response characteristics of dynamic behaviour were obtained,and the security of steel-structural factory building was verified.The results would be helpful for the design and construction of similar buildings.
