摘　　要：为降低结构施工难度并增大使用层空间,某市公共学习中心钢结构工程项目采用上挂下撑且从上到下附加临时支撑的施工方法。结果表明:拱形结构采用无支撑安装可有效缩短安装时间,结构整体稳定,施工简单;上挂下撑结构从下部施工时,底部采用临时支撑柱可满足受力与安全要求,卸载临时支撑柱后整体结构仍保持稳定,施工方法可行。In order to reduce the difficulty of structural construction and increase the use of floor space,the steel structure project of a public learning center in a city adopts the construction method of hanging up and down support and adding temporary support from top to bottom.The results show that the steel arch installation without support can effectively shorten the installation time,the overall structure is stable,and the construction is simple.When the upper hanging and lower supporting structure is constructed from the lower part,the temporary supporting column at the bottom can meet the requirements of stress and safety.After the temporary supporting column at the bottom is unloaded,the overall structure remains stable,and the construction method is reliable.
