摘　　要：依托杭州光环梦中心项目,对大跨度空间钢结构天窗采用分件吊装拼装法施工技术进行研究。主要介绍临时支撑体系、分片吊装施工技术以及如何利用BIM建模和Midas有限元相关数据分析确保施工安全。项目采用“一整体、二分片、三补缺”的方式进行吊装,全过程采用BIM建模和Midas有限元对天窗钢结构的安装和卸载过程进行了应力、应变仿真分析并对卸载完成后的天窗结构进行定期监测分析。研究结果表明,在现场条件受限或采用整体吊装方式费用支出较大时,利用现场设置临时支撑台架分件吊装安装施工具有一定的推广价值。Relying on the project of Hangzhou Guanghuan Dream Center,the construction technique of large-span space steel structure skylight using the method of piece-by-piece hoisting and assembly is studied.This paper mainly introduces the temporary support system,the construction technology of piecemeal hoisting,and how to use BIM modeling and Midas finite element analysis to ensure construction safety.The project adopts the method of"one whole,two pieces,three supplements"for hoisting,and the whole process uses BIM modeling and Midas finite element to simulate and analyze the stress and strain of the skylight steel structure during installation and unloading,and regularly monitor and analyze the skylight structure after unloading.The results show that when the site conditions are limited or the cost of integral hoisting is large,it has a certain promotional value to use the temporary support platform to hoist and assemble separately.
