［摘要］郴州市體育場主體采用鋼筋混凝土框架結(jié)構(gòu)，屋蓋采用空間鋼桁架結(jié)構(gòu)?？紤]混凝土和鋼結(jié)構(gòu)協(xié)同工作，有必要對其進行整體分析。在對結(jié)構(gòu)進行整體分析計算時，重點和難點是超長結(jié)構(gòu)設(shè)計和確定鋼弧柱的計算長度系數(shù)。計算結(jié)果表明，降溫荷載會使樓板中產(chǎn)生較大拉應(yīng)力，樓板開洞部位拉應(yīng)力集中；鋼弧柱的平面內(nèi)計算長度系數(shù)和平面外計算長度系數(shù)介于兩端理想剛接和一端鉸接一端剛接兩種情況之間。

Abstract: The major structure of Chenzhou Stadium adopts reinforced concrete frame structure and the roof adopts spatial steel truss structure. With consideration of the synergism of concrete and steel structure, it is necessary to analyze the overall structure. The design of super long structure and the determination of effective length factor of steel arc column are important but difficult in the overall structure analysis and calculation.The calculated results show that cooling load leads to major tensile stresses in the floor and the tensile stresses concentrate on the opening in the floor. The in-plane effective length factor of steel arc column and its out-plane effective length factor fall in between the value obtained when two ends are ideally rigid connected and the value obtained when one end is hinged and the other end is rigid connected.
Keywords: stadium; structural design; buckling analysis; super long structure; effective length factor; simplified model
