装配式剪力墙结构预制外墙安装阶段的风荷载稳定分析

Analysis on Wind Load Stability During Precast External Wall Installation of Precast Concrete Shear Wall Structure

装配式剪力墙结构是一种工业化生产产品,其施工工艺和现浇结构有较大的不同。装配式剪力墙预制外墙的现场安装,较普遍采用塔式起重机吊装,钢管进行临时支撑。因预制外墙的受风面积较大,有必要对其抗风压的稳定性进行验算,确保安装过程中的安全性。

The assembly shear wall is an industrial production,and its construction technology is different from the cast-in-place structure.The installation of precast external walls is generally supported by tower cranes and temporary support by steel pipes.Because the wind area of precast outer wall is large,it is necessary to check the stability of its wind resistance,so as to ensure the safety during installation.
