圆钢管拱桁架屋盖结构静力性能有限元分析

Finite element analysis of static performance of roof structure with circular steel tubular arch-truss

通过考虑十种不同的荷载工况组合,对某体育馆的圆钢管拱桁架屋盖结构进行了承载力分析,从而得到了结构杆件的内力分布、支座反力,并考虑两种不同的位移荷载工况,以了解结构的整体变形情况,分析结果表明,该拱桁架结构的强度及变形能满足要求,可为结构选型、构件截面设计提供参考。

Based on considering ten types of load combination, load-bearing capacity of roof structure with circular steel tube trues of one stadium is analyzed. The inner force distribution of members, reaction forces are obtained. Two different types of load combination for analyzing displacement case are also considered. The analyzed results show that the strength and deformation of this arch-trures can meet requirements. It may be a reference for structural type-selection and cross-section design.
