［摘要］青海科技馆主展馆平面为大曲率的弧线形，建筑层数、层高、建筑高度及跨度从建筑一端到另一端连续变化，建筑外立面向内外两侧倾斜，形状不规则，造型独特。弧形主展馆采用了下部为钢筋混凝土框架、上部为大跨度钢框架的独特的混合结构体系。椭球形中心展馆长轴80m、短轴50m、高33m，跨度及高度均为国内罕见，采用节点直接相贯的矩形钢管单层钢网壳结构体系。整体结构设计很好地满足了建筑功能造型需要并取得了较好的经济性指标。［关键词］青海科技馆; 大跨度结构; 混合结构; 单层钢网壳; 相贯节点中图分类号：TU318.2 文献标识码：A 文章编号：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
