摘要
以湛江某大学综合馆为工程背景,采用大型有限元分析软件ANSYS实现了异型网壳的建模,在确定构件设计截面后,研究了异型网壳结构的静力计算及其内力位移分布规律,并对它的整体稳定性进行了分析.最后,得出了对工程设计有益的结论.
Utilizing the finite element analysis software——ANSYS, a special double-layers lattice shell based on geometric model of parameters is designed and the area of the bar is selected on the basis of the danger case. The static analysis and the stability analysis are carried out based on the selected bar. The whole process leads to the beneficial conclusion for the design of the lattice shell.
