摘要
某体育馆钢屋盖为大跨度弦支穹顶结构。对结构布置和构件的尺度进行了研究,探讨了拉索的预拉力取值原则,设计了结构的预应力初始态,分别进行了弹性和弹塑性极限承载力计算分析。发挥了弦支穹顶结构体系的优势,符合结构设计的各项规定,同时又很好地满足了建筑设计的要求。对弦支穹顶结构体系的推广应用具有一定的参考价值。
The steel roof structure of a gymnasium is a kind of large span string-dome structure system.The structure layout and the dimension of structural members,the determination rules of pretension value for the prestressed cables are explored, the initial prestress state of the structure is designed,elastic and elasto - plastic ultimate bearing - capacity are analyzed respectively. This project employed the string-dome structure system's advantage,and corresponding structural design regulations are complied with,and at the same time,the requirements of architecture design is satisfied perfectly.
