Abstract: The 163 x 100m roof structure of Boeing hangar at Pudong airport consists of truss and steel frames. A general construction plan of“ground assembly and twice in tegral lifting” was employed. The program and its key technologies such as safeguard mesures in the air and load transferw ere described. Besides, integral lifting via MIDAS/Gen calculation was expounded. Based on analysis of structure stress and change rule of joints displacements, certain measures were adopted to achieve synchronous lifting, making the 2000-t steel structure successfully lift 34 meters.
Key words: Boeing hangar, truss, twice integral lifting, load transfer
摘要: 浦东机场波音机库屋盖结构跨度为163m,进深100m,由网架和门前钢桁架构成,施工过程中采用了??地面 拼装,两次整体提升的安装方法。详细论述了该方案及其空中停留保障措施、负载转移等关键技术,采用有限元 软件MIDAS/Gen全过程仿真计算整体提升过程;分析了两次提升过程中结构内力和节点位移变化规律,并采取措 施实现同步提升,成功地将2000多t钢屋架整体提升34m。
关键词: 波音机库, 网架, 两次整体提升, 负载转移
