基于上海市浦东新区某工程单层球面网壳设计,对球面网壳的选型因素,包括网格形式、网格密度、构件尺寸及施工因素进行了阐述。文中还通过不同网格密度的模型对比计算分析不同网格密度对网壳结构的稳定性能、用钢量及施工难度的影响。还列举了单层网壳结构设计应注意的其他问题。 Based on the design of single-layer spherical reticulated shell of a project in Pudong New Area in Shanghai, the selection factors of the reticular shell, including the grid form, grid density, component size and construction factors, are described. In this paper, the stability of grid-shell structure, the amount of steel used and the difficulty of construction are also analyzed and contrasted by the models with different grid densities. Other problems that should be noticed in the design of single-layer reticulated shell are also listed.
