摘要: 上海體育場作為承辦 2021 年世俱杯開閉幕式和總決賽的場地,按照國際足聯(lián)(FIFA)相關(guān)的場地要求,需對現(xiàn)有場地及相應(yīng)的設(shè)施進(jìn)行改建. 改建主要有四個(gè)方面:接待區(qū)域升級、場芯下挖 1. 7m、首層看臺(tái)上抬約 1. 8m和屋蓋鋼結(jié)構(gòu)懸挑向內(nèi)延展 16. 5m,其中屋蓋改建方案填補(bǔ)了國內(nèi)在既有空間鋼結(jié)構(gòu)上進(jìn)行大比例懸挑延伸改建的空白. 為實(shí)現(xiàn)屋蓋如此大比例的懸挑延展,既有屋蓋鋼結(jié)構(gòu)在新增結(jié)構(gòu)施工前,進(jìn)行了負(fù)載狀態(tài)下的加固,包括改變結(jié)構(gòu)體系的加固、受力轉(zhuǎn)換的加固和桿件與節(jié)點(diǎn)的補(bǔ)強(qiáng)加固,保障了結(jié)構(gòu)的安全. 同時(shí)為了體育場與科技的完美融合,設(shè)計(jì)中在新增懸挑段中滿布設(shè)置了 LED 天幕和南北側(cè)兩塊大屏,給觀眾更好的觀賽體驗(yàn).

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.
