摘　　要：钢连廊结构是高层建筑群之间用于联系的常用结构。因高空安装、跨度大、重量大及受建筑空间限制等特点,高空大跨度非对称钢结构连廊提升一直是建筑结构研究的重难点。针对其施工难点,提出“分区拼装,阶段提升,高空组装”的思想,以某工程高空大跨度非对称钢结构连廊的提升方案为基础,通过深化设计悬挑支架、提升支架、转换钢梁等实现了高空大跨度非对称钢结构连廊提升,并运用midas Gen等软件进行数值模拟计算证明了方案的安全性和可行性,为施工现场受限和特殊结构的钢连廊提升提供了新的施工思路。Steel corridor structure is a common structure used for connecting high-rise buildings.Because of its high altitude installation,large span,large weight,and limited building space,it has always been a key and difficult point in the study of building structure that lift large span of asymmetrical connecting steel corridors structure with high elevation.Aiming at the construction difficulties,the idea of sectional assembly,stage lifting and high-altitude assembly was put forward,and the cantilever support,lifting support,and steel beam type conversion were further designed to achieve the large span of asymmetrical connecting steel corridors structure with high elevation based on the lifting scheme for the connecting steel corridors structure lifting technology of a certain project.Numerical simulation with software such as midas Gen was used to prove the safety and feasibility of the scheme,which provided a new construction idea for the construction site limited and special structure of steel connecting corridor lifting.
