摘要: 上虞体育会展区体育场建筑高度约 33. 8m,屋面悬挑罩棚呈椭圆环形,长轴约 223m,短轴约 194m,设计为立体钢管桁架结构体系,下部采用钢筋混凝土框架结构体系。 对混凝土结构及钢罩棚的整体设计及几个关键方面进行了整理分析,主要介绍了结构体系、K 形框架、Y 形柱、钢罩棚整体稳定性、支座选取等内容,并采用非线性有限元软件建立实体单元模型对受力复杂的关键 K 形框架节点和钢支座处焊接空心球节点进行分析。 分析结果表明,结构整体设计合理,各项性能指标均能满足规范要求。

Abstract:The architectural height of the stadium in Shangyu Sports Exhibition Area is about 33. 8m. Its cantilevered roofcanopy is oval ring, with the long axis of about 223m and the short axis of about 194m. The roof canopy adopts threedimensional steel pipe truss structural systemand, the sub-structure adopts steel concrete frame structural system. Theoverall design and several key aspects of the concrete structure and steel canopy were sorted out and analyzed, including thestructural system, K-shaped frame, Y-shaped column, overall stability of the steel canopy, support selection, etc. And thenonlinear finite element software was used to establish a solid element model to analyze the key K-shaped frame joints andthe welded hollow spherical joints at the steel supports with complex forces. The analysis results show that the overall designof the structure is reasonable, and each performance index can meet the requirements of the specification.

Keywords: stadium; large-cantilevered structure; steel canopy; K-shaped frame; Y-shaped column; welded hollowspherical joint
