摘　　要：广州增城大球场建筑方案新颖、独特,结构设计利用建筑上人字拱的造型,采用拱-索-网壳结构体系,与建筑方案交相辉映。通过对结构体系进行简要介绍,采用MIDAS和ANSYS软件对球场东罩棚钢结构进行各工况下的设计计算和对比分析,并对部分关键节点进行精细化设计,使其能够较好地满足承载力及使用功能的要求。分析结果表明:拱-索-网壳结构体系可以有效地提高扁平网壳的整体稳定性,控制风吸作用下的变形和减小风吸作用下对柱顶的巨大拉力。The architecture scheme of the Zengcheng Big Ball Stadium is very novel, According to the architecture scheme, a new structure system named arch-cable-latticed shell was proposed, which was matched with the architecture scheme very well. StrUcture design and contrast analysis of east roof were made by MIDAS and ANSYS softwares in all load cases to make sure the calculation results could meet design requirements. And the special joints were also studied in this paper. The calculation and analysis results indicate that arch-cable-latticed shell structure system could improve the overall stability of the flat shell effectively, control the deformation in wind load case and decrease the big pulling force on the top of columns.
