摘要
国家会议中心二期工程横跨北京市城市道路大屯北路,需设置钢桁架及吊挂结构。施工中采用支撑体系分段原位安装的方案,提高了安装精度,解决了钢结构下挠变形问题,缩短了施工工期,卸载后大跨度钢桁架及钢梁挠度值及应力监测值均符合设计要求。
China National Conference Center Phase Ⅱ spans across Beijing's urban road Datun North Road and requires steel trusses and hanging structures.In the construction,the support system is installed in-situ in sections,which improves the installation accuracy,solves the problem of deflection and deformation of the steel structure,and shortens the construction period.After unloading,the deflection value and stress monitoring value of the large-span steel truss and steel beam conform to the design Claim.
