摘　　要：随着我国建筑材料工业的不断进步,许多新型的建筑结构形式得以实现,其中预应力钢结构的发展尤其迅速.本文结合四川省博物馆采光天棚的工程实例,分析了张拉筒壳结构在不同结构状态的受力机理,对索的初始预拉力值确定、结构的内力和变形计算、杆件及节点设计等关键问题进行了较为深入的分析,得出了一些有益的结论.As the development of building material industry, some new types of structures have come true, such as prestressed steel structures which have made a rapid progress in recent years. The work mechanism of cable stayed cylindrical shell in different structure status was investigated based on the structure for Sunshade of Sichuan Museum. Analysis was carried out on the key issues, such as cable prestress value, force and deformation calculation, member and joint design and so on. Finally some useful conclusions were brought forward.
