[摘要]根据风洞试验结果和建筑造型需要确定长春奥林匹克公园体育场屋盖膜结构的造型。按照位移控制指标进行索膜结构预应力设计。首次将C80的高强混凝土运用到钢结构桁架中,充分发挥了钢筋混凝土抗压能力强、造价低廉的优势。分别对膜、索、支座等关键部位进行抗连续倒塌分析,确保结构的整体稳定性,并对关键节点进行了优化设计。

Abstract:According to the wind tunnel test results and the needs of architectural modeling, the shape of  membrane structure roof of Changchun Olympic Park Stadium was determined. The prestressing design of the cable membrane structure was carried out according to the displacement control index. The high-strength concrete of C80 was applied to the steel truss for the first time to fully exert the advantages of strong compressive strength and low cost of reinforced concrete. The anti-progressive collapse analyses were carried out respectively on key parts such as membrane, cable and support to ensure the overall stability of the structure. The key nodes were optimized and designed.

Keywords:Changchun Olympic Park Stadium; prestressed design; high-strength concrete; concrete-filled steel tube ring truss
