钢柱施工侧移引起的装配式钢结构住宅整体安全性分析

Analysis of the Overall Safety of Prefabricated Steel Structure Houses Caused by the Lateral Movement of Steel Column Construction

在当前新时期背景下,建筑施工技术发展速度不断提升,各种新技术涌现为建筑施工效率与质量提升提供坚实技术基础。装配式施工技术因其施工效率高、环保性强等优势,近年来受到建筑行业的广泛关注与应用,然而需注意的是,装配式住宅承重钢柱节间安装过程中,会因焊接质量或本身制作误差导致建筑整体或层级产生位移,并造成楼层应力应变分布失衡,严重威胁住户安全。基于此,论文首先对装配式钢结构建筑进行概述,并结合实际案例,构建装配式钢结构住宅数值计算模型,以此为依据对其整体安全性进行探究。

In the context of the current new era,the development speed of building construction technology is constantly improving,and various new technologies are emerging to provide a solid technical foundation for the improvement of construction efficiency and quality. Prefabricated construction technology has received widespread attention and application in the construction industry in recent years due to its high construction efficiency and strong environmental friendliness. However, it should be noted that during the installation process of load-bearing steel columns in prefabricated residential buildings,the overall or hierarchical displacement of the building may occur due to welding quality or manufacturing errors, resulting in an imbalance in the distribution of floor stress and strain, which seriously threatens the safety of residents. Based on this, the paper first provides an overview of prefabricated steel structure buildings,and combines practical cases to construct a numerical calculation model for prefabricated steel structure residential buildings,based on which the overall safety is explored.
