某双层球面网壳结构设计

Structural design of the double-layer spherical reticulated shell

针对某体育中心屋盖设计过程中运用3D3S空间结构计算软件进行设计计算,并对各荷载工况组合下杆件应力比和结构动力特性等进行了分析,从分析结果来看,该结构的刚度和结构振型能够符合使用要求,杆件承载力、稳定和结构变形均能满足规范要求,结构设计合理。

Abstract： In light of the roof design, the paper applies 3D3S space structural calculation software for design calculation, and analyzes member stress and structural dynamic characteristics under various loading conditions. The analysis results show that： the structural rigidity and structural vibration meet demands ; the member bearing, stability and structural deformation meet demands; the structural design is rational too.
