管廊钢桁架的设计

Design of Steel Truss for Pipe Gallery

钢桁架是一种比较常用的结构形式。在化工项目中,大跨度管廊、大跨度屋面、输煤栈桥等均采用钢桁架结构形式。论文结合工程实际,分别对比剖分T形钢、H形钢和传统的双角钢桁架在工程性能中的优缺点,并分析桁架因高度不同而内力变化的优化设计。

Steel truss is a kind of common structure.In chemical engineering projects,large-span pipe gallery,large-span roof and coal handling trestle all adopt steel truss structure.In this paper,the advantages and disadvantages of T-section steel,H-section steel and traditional double-angle steel trusses in engineering performance are compared,and the optimal design of internal force variation due to different height of trusses is analyzed.
