摘要
上海浦东足球场整体结构由一层地下室结构、地上钢结构看台和大跨度钢结构屋盖三部分组成,地上看台结构采用钢框架+屈曲约束支撑体系,屋盖采用轮辐式张拉体系。屋盖和下部结构单独分析,不能体现上下结构之间的相互影响。为更可靠合理进行整体结构设计,采用了整体模型分析作为单体模型分析的重要且必要的补充。整体模型分析工作主要包括多遇地震、设防地震下的弹性分析,罕遇地震下的弹塑性时程分析,以及超长混凝土结构应力分析。结果表明:单体分析存在局限性,整体模型的足球场结构受力安全。
Shanghai Pudong Football Stadium is composed of three parts:the first-floor basement structure,the ground stand steel structure,and the large-span roof steel structure.The ground stand structure adopts the steel frame+buckling restraint brace system,and the roof adopts the spoke tensioning system.The roof and substructure were analyzed separately,and the interaction between the upper and lower structures cannot be reflected.To design the overall structure more reliably and reasonably,the overall model analysis was adopted as an important and necessary supplement to the single model analysis.The overall model analysis mainly includes the elastic analysis under frequent earthquakes and fortification earthquakes,the elastic-plastic time history analysis under rare earthquakes,and the stress analysis of super-long concrete structures.The results show that there are limitations of monomer analysis,but the overall model of football field structure is safe.
