摘  要:义马体育馆罩棚设计平面近似为相互咬合的两个平行四边形。为满足建筑外观及室内感官的要求,屋面罩棚结构形式采用支承于三角形格构柱上双向斜交管桁架结构。结构形式新颖美观,通过分析,结构强度及刚度可以满足规范的要求,结构稳定性较好。介绍该结构体系设计的难点及解决方案,通过两种有限元软件进行分析对比,其计算结果基本一致,主要参数的差值均小于5%。The construction plane of Yima stadium canopy is similar with two occlusal parallelograms.To meet the construction requirements of exterior and interior senses,the bidirectional bias pipe truss supported on the triangular lattice column was applied into the roof design.The structural form is fashionable and attractive.By analyzing,the structural strength and stiffness could meet the specification requirements,and the construction has good structural stability.This article described the difficulties in the design of structural systems and solutions,the analysis and comparison was completed with two type finite element softwares,the results are consistent,and the main parameters are less than 5% difference.
