摘　　要：某会展中心建筑平面造型近似椭圆形,屋顶结构为近似椭圆体钢结构。通过介绍椭圆形钢结构弧形钢梁分段吊装拼装施工特点和难点,详细阐述了弧形钢梁分段吊装拼装施工流程、施工要点、质量控制措施与仿真分析结果。实践证明分段吊装拼装技术方法可靠,能够最大限度地减少对施工场地的要求,提高施工质量,减少机械吊装台班量与难度,节约施工成本。A conference and exhibition center is oval plan, whose roof is oval steel structure. By analyzing the characteristics and difficulties of segmental hoisting and assembly construction of the oval steel structure arc beam, the arc beam segmental hoisting and assembly construction, construction points, quality control measures and the results of the simulation analysis are described in detail. Practice has proved that the segmental hoisting and assembly technology is reliable, can minimize the construction site requirements, improve the construction quality, reduce the rent amount and difficulty of hoisting machinery and save the construction cost.
