摘要
复杂支承条件下空间网架的静动力结构分析是网架分析中比较困难的一类问题。使用通用有限元分析软件对作者参与的深圳市民中心空间网架设计原方案进行了静动力结构分析 ,并对原设计方案进行了结构优化与调整。优化调整后的结构较原方案更有效地利用了材料的承载能力和结构刚度的整体性 ,从而既提高了结构的承载力和刚度 ,又降低了钢材的使用量。文中所给出的分析方法可供同类工程参考。
Static and dynamic structural analysis of spatial latticed grids with complicated supporting conditions is very difficult in the analysis of latticed grids.FEA software was applied to make the static and dynamic structural analysis of the schedule of spatial latticed grids in the Shenzhen Civil Center.Structural optimization is carried out for the original design scheme.The loading capacity of materials and integrity of the structural rigidity are more efficiently explored through optimization,so the loading capacity and rigidity are enhanced and consumption of steel is reduced.Analysis also shows the strong function of FEA software on the analysis of spatial latticed grids.
