［摘要］青海科技館主展館平面為大曲率的弧線形，建筑層數(shù)、層高、建筑高度及跨度從建筑一端到另一端連續(xù)變化，建筑外立面向內(nèi)外兩側(cè)傾斜，形狀不規(guī)則，造型獨特。弧形主展館采用了下部為鋼筋混凝土框架、上部為大跨度鋼框架的獨特的混合結(jié)構(gòu)體系。橢球形中心展館長軸80m、短軸50m、高33m，跨度及高度均為國內(nèi)罕見，采用節(jié)點直接相貫的矩形鋼管單層鋼網(wǎng)殼結(jié)構(gòu)體系。整體結(jié)構(gòu)設計很好地滿足了建筑功能造型需要并取得了較好的經(jīng)濟性指標。［關鍵詞］青?？萍拣^; 大跨度結(jié)構(gòu); 混合結(jié)構(gòu); 單層鋼網(wǎng)殼; 相貫節(jié)點中圖分類號：TU318.2 文獻標識碼：A 文章編號：1002-848X(2016)03-0054-05
Structural Design on Science and Technology Hall of QinghaiWang Chunguang, Liu Jiantao, You Tianzhi(China Architecture Design & Research Group, Beijing 100044, China)Abstract:The Science and Technology Hall of Qinghai is very special for the planar and spatial shape are all large curved. The number of floors, height of floors, building height and span are all varies from the two ends of the building. The facades incline from both sides，the shape is irregular and unique. Reinforced concrete frame structure is used for the low parts of the main arced exhibition hall and large span steel frame structure is used for upper part of the main arced hall. Single-layer steel reticulated shell structure is used for the ellipsoid center hall, which is very huge for the 80 meters major axis and 50 meters short axis, 33 meters height, and direct welded tubular joint is used. The structural design satisfied the architectural design concept very well and achieved good economic indicators.Keywords:Science and Technology Hall of Qinghai; large span structure; hybrid structure; single-layer steel reticulated shell; tubular joint
