摘　　要：首都博物馆东馆梭形柱为摇摆柱、屋面弧形梁、南侧悬挑梁,若不采取防变形控制措施,很难达到设计要求,且存在很大的安全和质量风险。本研究详细介绍了首都博物馆东馆钢结构施工的变形控制措施,对主楼屋面、梭形柱钢结构施工前进行施工全过程模拟分析,待结构安装到位后进行卸载,分析卸载过程中结构变形及受力情况。In the East Hall of Capital Museum,the shuttle-shaped columns are leaning columns,curved beams are used on the roof,and cantilever beams are used on the south side,which signifies that if no anti-deformation control measures are adopted,it will be difficult to meet the design requirements and there will also be a great risk of safety and quality.In this paper,the deformation control measures for the steel structure construction of the East Hall of Capital Museum are introduced in detail,the whole construction process is simulated and analyzed before the construction of the main building roof and the steel structure of shuttle-shaped columns,and the structure deformation and stress conditions during the unloading after the structure has been installed are also analyzed.

关 键 词：梭形柱 弧形梁 卸载分析 变形控制
