摘要: 上海体育场作为承办 2021 年世俱杯开闭幕式和总决赛的场地,按照国际足联(FIFA)相关的场地要求,需对现有场地及相应的设施进行改建. 改建主要有四个方面:接待区域升级、场芯下挖 1. 7m、首层看台上抬约 1. 8m和屋盖钢结构悬挑向内延展 16. 5m,其中屋盖改建方案填补了国内在既有空间钢结构上进行大比例悬挑延伸改建的空白. 为实现屋盖如此大比例的悬挑延展,既有屋盖钢结构在新增结构施工前,进行了负载状态下的加固,包括改变结构体系的加固、受力转换的加固和杆件与节点的补强加固,保障了结构的安全. 同时为了体育场与科技的完美融合,设计中在新增悬挑段中满布设置了 LED 天幕和南北侧两块大屏,给观众更好的观赛体验.

Abstract: As the venue for hosting the opening and closing ceremonies and finals of the 2021 World Club Cup, ShanghaiStadium needs to renovate the existing venue and corresponding facilities following the venue requirements of FIFA. Thereconstruction mainly includes four aspects: the upgrading of the reception area, the excavation of the field core of 1. 7m,the lifting of the first-floor bleachers of about 1. 8m, and the extension of the roof steel structure cantilevered inward of16. 5m. The roof reconstruction scheme fills the gap of large-scale cantilever extension reconstruction on the existing spatialsteel structure in China. To achieve such a large-scale proportion of cantilevered extension of the roof, the existing roof steelstructure has been strengthened under the necessary load state before the construction of the new structure, includingchanging structural system, stress transformation, rod and joint reinforcement, which ensure the safety of the structure. Atthe same time, the new cantilevered section was covered with LED screens and two large screens on the north and southsides for the perfect integration of the gymnasium and technology, giving the audience a better viewing experience.
