摘要
针对南京江宁主体育场看台顶篷桅杆斜拉钢网壳的拉索张拉,介绍了前索调整索长、后索张拉成形的施工方法,分析了预应力初始态、支架支撑状态以及张拉过程中结构的反应,优化了施工方案,掌握了张拉过程中索力变化和结构变形的规律,为拉索施工和张拉监测提供了依据。
This paper introduces the cable tension method of prestressed lattice shell structure in the stadium of Jiangning Nanjing. The structure, in prestressed initial state, in scaffolding state and during tension process is analyzed to optimize the tension scheme, master the cable-force variation and mast deformation during tension process, and provide gist for cable tension and monitor.=
