摘要
网壳结构是空间结构中常见的结构形式,利用ANSYS有限元分析方法,对局部双层网壳结构进行了地震作用时程分析计算,得到了结构杆件的内力和节点的位移,对结构动力响应在线性、几何非线性及几何和材料非线性情况下进行了分析对比。分析结果表明,网壳结构在三维地震作用下应该考虑几何和材料非线性的影响。
Reticulated shell is one type of the common spatial structure form.This paper calculates the seismic performance on the optimum partial double layer reticulated shell by ANSYS,gains the stress of members and nodal displacements,and compares the linear,geometric nonlinear and geometric and material nonlinear dynamic responses,which indicates that geometric and material nonlinear isn't neglected in the analysis of reticulated shell on the 3-dimensional earthquake.
