对圆柱面杆系巨型网格结构 ,文中就其子结构的布置、组合杆的计算、结构整体优化计算方法等进行了分析 ;通过是否考虑两者协同承载、有无主体结构上弦杆的对比分析 ,综合考虑构造因素 ,就子结构的布置提出了两种比较优越的巨型网格结构形式 ,并对巨型结构形式与普通双层网壳就用钢量方面进行了对比分析 ,提出了各结构形式的适宜跨度范围。
In this paper, the giant grid structure of cylindrical rod system is analyzed in this paper. The sub-structure layout, the calculation of composite rod and the overall optimization calculation method are analyzed. By considering whether the two are co-supported or not, Considering the structural factors synthetically, two kinds of superior mega-grid structures are proposed in terms of the arrangement of the sub-structures. The comparative analysis of the mega-structural forms and the ordinary double-layer reticulated shells in terms of the amount of steel used is presented, and various structural forms The appropriate span range.
