［摘要］中國石油大廈工程由高度90m的四棟22層的L形辦公樓組成，其中中間兩座為連體，連體下方主中庭為工程結構突出的亮點。主中庭屋蓋采用雙向張弦結構，中庭內(nèi)設置聯(lián)系兩側主體塔樓的吊橋，懸吊在主中庭屋蓋上，吊橋兩邊與主體結構剛性連接。中庭建筑立面為單層索網(wǎng)幕墻，采用單層索網(wǎng)結構，立面鋼雨篷采用背索平衡，背索與幕墻索網(wǎng)共同作用，平衡雨篷鋼梁。為了結構安全和使用方便，進行了大量計算分析，確定了索的初始張拉力、直徑，對這種結構的設計方法、計算方法進行了研究。施工過程中實測數(shù)據(jù)與計算結果的對比驗證，為今后類似工程提供了一定的參考。

Atrium cable structure design of the Petroleum Building of China
Chen Lin, Shu Weinong (Beijing Institute of Architectural Design, Beijing 100045, China)
Abstract:The Petroleum Building of China is contained four L-shaped office buildings with 22 floors, 90m height. In side of these buildings, the two buildings is connected. The main atrium under the connected-structure is the outstanding character of this project. The main atrium roof adopts two-way string structure. A suspended bridge connects the main body tower inside of the main atrium with rigid connection, which is suspended on the roof of the main atrium. The elevation of the atrium building adopts single-layer cable nets structures. The elevation rain-cover is balanced by the back cable, which can combine action with curtain-wall cable to make the steel beam balance of rain-cover. A great deal of calculation analysis were done to make sure the safety and the using convention. The method of how to gain the initial tensioning force and diameter of the cable is proposed. The calculation and the design method of the structure are researched. The measured data obtained from the construction process are compared with calculation results to provide basis for future similar projects.
Keywords:connected high-rise building; main atrium; two-way string structure; suspended bridge; single-layer cable nets; cable
