针对水泥工厂预均化库屋盖结构工程,选取跨度60 m双层柱面网壳进行优化设计,分析了对其性能及用钢量的影响要素,结果表明地震作用对用钢量影响很小,而风荷载是网壳结构设计的控制荷载。%According to the roof structural project at the pre-homogenization store of cement plants, the paper undertakes the optimal design for the 60 m double-layer cylindrical lattice, analyzes it performance and the influential factors of its steel consumption, and proves by the result that the earthquake has little influence on its steel consumption while the wind loading is the controlling loading of the lattice structure design.
