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。
In view of the steel structure design of Shanghai Natural Gas Dispatching and Command Center, the structural arrangement and connection structure processing adopted to avoid plane and vertical irregularities are introduced in detail. The large-span shared hall uses large-diameter steel pipe columns and space tube trusses to improve the structural lateral stiffness, and adopts fish-belted trusses and prestressed cable trusses to meet the requirements of the building and structure in the design of long-span point-shaped glass curtain walls. The value of load calculation parameter and prestress control of cable.
