［摘要］長春奧林匹克公園游泳館總建筑面積約34 000m2，平面為橢圓，長軸163m，短軸115m，屋頂為單向傾斜面，屋頂高度為20-05～34-7m。主體結(jié)構(gòu)為鋼筋混凝土框架結(jié)構(gòu)，屋蓋及斜柱采用鋼結(jié)構(gòu)。結(jié)構(gòu)外觀呈橢圓倒錐體幾何造型，周邊52根斜柱與地面夾角為50°左右，呈發(fā)散形，屋蓋最大跨度70m，形成頭重腳輕的態(tài)勢。闡述了本工程結(jié)構(gòu)體系、布置、節(jié)點、方案選型等方面內(nèi)容，并著重闡述了本結(jié)構(gòu)的創(chuàng)新點，即設(shè)計中讓外圍斜柱、部分內(nèi)部直柱子與大跨度屋蓋形成耦合受力的結(jié)構(gòu)。結(jié)合實際工程提出了斜柱與大跨度屋蓋耦合受力的設(shè)計方法，可為同類工程設(shè)計提供參考。

Abstract:Changchun Olympic Park Swimming Gym has a total construction area of 34 000 square meters. The plane is elliptical, with a long axis of 163 meters and a short axis of 115 meters. The total roof is a one-way inclined surface with a roof height between 20-05 meters to 34-7 meters. The main structure is a reinforced concrete frame structure, and the roof and the inclined column adopt steel structure. The structure is in the shape of an elliptical inverted cone. The angle of the 52 surrounding inclined columns and the ground is about 50°, showing a divergent shape. The maximum span of the roof is 70m, forming a top-heavy posture. The structural system, layout, nodes, scheme selection and other aspects of the project were expounded, and the innovation of this structure was highlighted to make the peripheral inclined columns and part of the inner straight columns to form a coupling mechanical structure with the large-span roof in design. Combined with the actual project, the design method of coupling force between the inclined columns and the large-span roof was proposed, providing reference for similar engineering design.
Keywords:Changchun Olympic Park Swimming Gym； inclined column; large-span roof; coupling force
