摘要
以山西太原某商业房地产项目为研究对象,分析了大型钢结构综合支吊架的施工工艺,并运用数值模拟的手段对综合支吊架的应力比、稳定性和位移进行计算。研究结果表明,综合支吊架应力比为0.1~0.3,稳定性范围为0.0~0.3,位移范围为L/184857~L/90,故其满足设计要求;不同长度的横梁位移荷载曲线变化规律大致相同,随着横梁长度的增加,横梁的屈服荷载和极限荷载均呈线性降低,在实际工程综合支吊架的施工安装中,应针对管道和线路的位移变形要求,对横梁的长度进行最优选择。
Taking a commercial real estate project in Taiyuan city,Shanxi province as the research object,the construction process of large-scale steel structure comprehensive support and hanger was analyzed,and numerical simulation was used to calculate the stress ratio,stability,and displacement of the comprehensive support and hanger.The research results indicate that the stress ratio range of the comprehensive support and hanger is 0.1~0.3,the stability range is 0.0~0.3,and the displacement range is L/184857~L/90,which meets the design requirements.The variation law of the displacement load curve of beams with different lengths is roughly the same.As the length of the beam increases,the yield load and ultimate load of the beam decrease nearly linearly.In the construction and installation of comprehensive support and hanger in practical engineering,the optimal selection of the length of the beam should be based on the displacement deformation requirements of pipelines and pipelines.
