大跨度钢结构倾斜柱后激活施工技术

The After-activation Construction of Large-span Steel Structure Inclined Column

本工程施工过程中,结合设计引入的后激活施工的理念,通过实际施工模拟分析以及施工时期的应力监测应用,以实现大跨度空间异形结构中部分支撑钢柱的后激活,利用原受拉支撑钢柱先承担结构荷载,从而优化截面,节省材料用量。

During the construction,combining with the design introduced after-activation construction concept,through the actual construction simulation of stress monitoring application analysis and construction period,it achieves the supporting columns of large span space structure of special-shaped after activation,using the original tensile brace steel post first bear the loads on the structure,thus optimizing the section,saving amount of material.
