某体育馆大跨度球面网壳设计分析

Design analysis of a stadium long-span spherical latticed shell

论述了某体育馆比赛馆屋面网壳的设计思想,对三向及角锥网格和二向及平面桁架网格进行了比较,采用MSTCAD和有限元软件ANSYS对网壳进行了静力分析和整体稳定性分析,研究了不同边界约束下支座的受力模型和设计,并提出了在大跨度网壳设计中应予以考虑的若干关键问题。

This paper discusses the design philosophy of a space latticed shell roof of a competition venue in a stadium.A study was conducted though making a comparison between a three-way pyramid latticed shell and a twoway plane truss latticed shell,carrying out a static and global stability analysis by using MSTCAD software and FEA analysis software ANSYS,and investigating models with different boundary conditions of the support along with support design.Furthermore,several key problems that should be considered during the design of long-span space shell structures are presented.
