[提要] 隨著我國建筑材料工業(yè)的不斷進步，使得許多新型的建筑結構形式得以實現(xiàn)，其中預應力鋼結構的發(fā)展尤其迅速。本文結合四川省博物館采光天棚的工程實例，分析了張拉筒殼結構在不同結構狀態(tài)的受力機理，對索的初始預拉力值確定、結構的內力和變形計算、桿件及節(jié)點設計等關鍵問題進行了較為深入地分析，得出了一些有益的結論。

Cable Stayed Tube Shell Design for Sunshade of SiChuan Museum / Ding Dayi
(Wuzhou Engineering Design and Research Institute, Beijing 100053, China)
Abstract: As the development of building materials industry, some new type structures have
come true. Especially prestressed steel structures, who have made a rapid progress in recent
years. The work mechanism of cable stayed tube shell in different structure status was
presented with the Sunshade case 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.
