［摘要］根據(jù)風(fēng)洞試驗(yàn)結(jié)果和建筑造型需要確定長春奧林匹克公園體育場(chǎng)屋蓋膜結(jié)構(gòu)的造型。按照位移控制指標(biāo)進(jìn)行索膜結(jié)構(gòu)預(yù)應(yīng)力設(shè)計(jì)。首次將C80的高強(qiáng)混凝土運(yùn)用到鋼結(jié)構(gòu)桁架中，充分發(fā)揮了鋼筋混凝土抗壓能力強(qiáng)、造價(jià)低廉的優(yōu)勢(shì)。分別對(duì)膜、索、支座等關(guān)鍵部位進(jìn)行抗連續(xù)倒塌分析，確保結(jié)構(gòu)的整體穩(wěn)定性，并對(duì)關(guān)鍵節(jié)點(diǎn)進(jìn)行了優(yōu)化設(shè)計(jì)。

Abstract:According to the wind tunnel test results and the needs of architectural modeling, the shape of  membrane structure roof of Changchun Olympic Park Stadium was determined. The prestressing design of the cable membrane structure was carried out according to the displacement control index. The high-strength concrete of C80 was applied to the steel truss for the first time to fully exert the advantages of strong compressive strength and low cost of reinforced concrete. The anti-progressive collapse analyses were carried out respectively on key parts such as membrane, cable and support to ensure the overall stability of the structure. The key nodes were optimized and designed.

Keywords:Changchun Olympic Park Stadium; prestressed design; high-strength concrete; concrete-filled steel tube ring truss
