| 摘 要： | 弦支穹顶结构是一种刚柔杂交的预应力钢结构体系,实际工程少,施工经验不足,针对此结构的施工过程分析显得十分重要。基于非线性有限元原理,区分弦支穹顶结构的初始态和几何零状态,指出弦支穹顶的施工过程是结构从几何零状态到初始态的连续变化的过程,可以采用张力松弛法进行施工过程的模拟分析。通过分析2008年奥运会羽毛球馆屋盖的工程实例,考虑施工场地条件,确定下部索杆的张拉顺序,对结构施工进行全过程模拟分析。

| Abstract: | Suspendome is a prestressed steel structure that is mixed rigidity and flexibility.There are few actual structure and construction experience,so the analysis of construction process of a suspendome becomes increasingly important. Based on the non-linear finite element theory,differentiating initial prestress satate and zero state of suspendome,it is pointed out that the construction of suspendome is a sequence process from zero state to initial state.The release tension method can be used to simulate and analyse the construction process.By analyzing 2008 Olympic Games badminton gymnasium,the conditions of construction site are considered and tensile sequence of lower cable-strut is also decided,that all course analysis of the construction is simulated. |
