摘要
桐庐励骏酒店钢结构工程施工难点在于采用了大跨度巨型悬挑结构,最大悬挑长度达36m,其安装技术对主体结构整体性影响较大,在安装过程中对悬挑部分的支撑架卸载过程进行了三维仿真分析,并对悬挑结构进行了卸载过程中结构变形的监测。通过分析和监测,指导本工程的施工安装过程。
The construction difficulty of Legendale Hotel lies in the long-span giant cantilever truss used for the steel structure engineering.The maximum cantilever length is up to 36m and the installation technology of cantilever has great influence on the main structure integrity.The 3D digital simulation of the unloading process of the cantilever bracing system was conducted during installation,and the deformation monitoring of the cantilever was carried out during unloading process.The result of analysis and monitoring is used to guide the construction of this project.
