某大尺寸异型网壳结构的分析与设计实践

Analysis and Design Practice of a Large-scale Special-shaped Reticulated Shell Structure

文章研究了大空间、异型网壳结构在作为屋面结构时的曲面构建方法,结合实际工程,介绍了空间单层网壳的荷载分布、受力分析、设计过程。最后,通过屈曲分析确定了立柱的计算长度,通过多尺度分析方法找出节点薄弱位置,并针对性予以加强,确保了结构安全。

This paper studies the surface construction method of large space and special-shaped reticulated shell structure as roof structure.Combined with practical engineering,the load distribution,stress analysis and design process of space single-layer latticed shell are introduced.Finally,the effective length of the column is determined by buckling analysis.Through the multi-scale analysis method to find out the weak position of the node,and strengthen it pertinently to ensure the structural safety.
