摘要
通过对某中学体育馆方钢管桁架屋盖结构的设计和弦杆旋转45°放置的方钢管KK相贯节点的非线性有限元分析,表明倒三角形方钢管立体桁架受力合理,且支座的合理设计能有效改善整体结构的受力性能。基于有限元分析结果对方钢管KK节点提出设计的合理化建议。
It was introduced the design of the RHS truss roof system and the nonlinear analysis of KK rectangular tubular-joints whose chord members were rotated 45°.The result indicates that converse triangular RHS truss transfers force suitably.And the rational design of supports can ameliorate the total structural performance.Design suggestions on KK rectangular tubular-joints are offered based on the finite analysis.
