［摘要］介紹了黃石奧林匹克體育中心體育場(chǎng)的結(jié)構(gòu)選型與布置、分縫方案比選、復(fù)雜節(jié)點(diǎn)設(shè)計(jì)。下部主體結(jié)構(gòu)為鋼筋混凝土框架結(jié)構(gòu)，通過(guò)鋼筋混凝土空腹桁架傳遞鋼罩棚支座的水平反力，分縫方案可以顯著釋放下部混凝土結(jié)構(gòu)的溫度應(yīng)力，動(dòng)力特性也較好，是下部結(jié)構(gòu)的理想方案。鋼罩棚采用折形平面交叉鋼桁架+樹(shù)狀鋼支撐結(jié)構(gòu)體系，采用不分縫方案，除了鋼罩棚構(gòu)件溫度應(yīng)力小幅增加外，抗震性能、對(duì)下部混凝土結(jié)構(gòu)的影響都明顯優(yōu)于分縫方案，是鋼罩棚的理想方案。

Abstract:The structural system selection and layout, the comparison and selection of joint schemes, and the design of complex joints of the stadium of Huangshi Olympic Sports Center was introduced. The main structure of the lower part is reinforced concrete frame structure. The horizontal reaction force of the steel canopy support is transmitted through the reinforced concrete vierendeel truss. The joint scheme significantly releases the temperature stress of the lower part of the lower concrete structure, and the dynamic characteristics are also good. Therefore, it is an ideal scheme of the lower part of the structure. The steel canopy adopts folded plane cross steel truss + tree-shaped steel support structural system, and adoptes undivided joint scheme. In addition to the slight increase in the temperature stress of steel canopy members, the seismic performance and the influence on the lower concrete structure are obviously better than those of the joint scheme, which is an ideal scheme for the steel canopy.
