摘要(Abstract):

针对上海天然气调度指挥展示中心钢结构设计,详细介绍了为避免平面及竖向不规则而采用的结构布置和连接构造处理。大跨度共享大厅采用大直径钢管柱和空间管桁架以提高结构抗侧刚度,在大跨度点式玻璃幕墙设计中采用鱼腹式桁架及预应力索桁架以满足建筑和结构的要求,介绍了风荷载计算参数的取值及拉索的预应力控制。
It introduces the structural design of Shanghai Gas Command and Demonstration Center which includes the structure plane arrangement and the connecting constructions to avoid irregular planar and vertical structure,adoption of large diameter steel tube column and hollow structural section truss to improve the structure stiffness of the sharing hall.The adoption of parameters in calculating wind load and the prestress control of the pretensioned cable truss are presented in design of the large span glass curtain wall which adopted fish-bellied truss and pretensioned cable truss.
