摘　　要：某高层双塔楼钢结构连廊总重量1440 t,最大跨度57.275 m,大吨位超长跨钢结构采用整体液压同步提升施工技术。提升吊点位置、桁架临时加固及提升托座利用有限元分析进行方案设计、结构应力、变形分析与监测控制,保证了工程优质按期完成,可供类似工程参考。A high-rise twin tower steel structure corridor has a weight of 1440 ton and the maximum span is 57.275rn long. Synchronous integral hydraulic lifting technique was used for construction of the large-tonnage and super-long span steel structure. Finite element analysis was adopted for scheme design of lifting point, temporary truss strengthening and lifting base, as well as structural stress, deformation analysis and monitoring control, etc., to guarantee successful completion. References were provided for similar projects.
