我国网架、网壳等空间钢结构的推广应用,不论是工程数量还是覆盖建筑总面积,在国际上都是名列前茅的。但是这些结构往往有其不足之处。首先结构本身制作、安装复杂,结构施工工期长。其次这些结构的屋面防水、屋面围护结构的自重,都是制约工程总造价的因素。虽然理论上这类空间结构用钢量小,自
The popularization and application of space steel structures such as network shelves and lattice shells in China, both in terms of the number of projects and the total area covered by buildings, are among the best in the world. However, these structures often have their deficiencies. First of all, the structure itself is complicated to make and install, and the construction period is long. Secondly, the roof waterproofing of these structures and the self-respect of the roof envelope structure are the factors that restrict the total construction cost. Although theoretically this kind of space structure uses a small amount of steel,
