圆柱面杆系巨型网格结构由主体结构与子结构两级组成：主体结构为由组合杆构成的大网格结构，子结构为普通网架结构，布置于主体结构的大网格中。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进行了分析，并对几种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，提出了巨型网格结构的实用跨度范围。
The cylindrical grid giant grid structure consists of the main structure and the substructure. The main structure is a large grid structure composed of composite rods. The substructure is a common grid structure and is arranged in a large grid of the main structure. In this paper, the layout of its substructure, the calculation of the composite rod and the overall optimization of the structure are analyzed. Several giant structures and ordinary double-decker reticulated shell are compared and analyzed in terms of the amount of steel. The practical range of structures.
