摘要
大跨度钢结构吊装施工因可以节省大量临时支撑,减少高空作业,提高设备利用率及施工效率,成为钢结构施工的关键方法之一.论文以庐山站西站房钢结构大雨棚工程为背景,利用 ANSYS有限元方法进行施工过程的数值模拟,分析了西站房雨棚吊装施工过程中整体结构及临时结构的应力、位移变化.结果表明:该结构施工过程中的最大位移为 56.38 mm,最大应力为 214 MPa,临时胎架最大位移为 8.03 mm,位移和应力均未超过规范限值.模拟结果表明了工程施工过程的安全性,为类似工程的施工分析提供了参考.
Abstract
The large-span steel structure lifting construction has become a key method in steel structure construction due to its advantages of saving temporary supports,reducing high-altitude operations,and improving equipment utilization and construction efficiency.Taking the steel structure canopy project of Lushan West Station as the background,this study utilized the ANSYS finite element method to numerically simulate the construction process and analyzed the stress and displacement variations of the overall structure and temporary structures during the lifting construction of the canopy.The results showed that the maximum displacement in the construction process was 56.38mm,and the maximum displacement of the temporary support frame was 8.03mm.The displacements and stresses were within the limits specified by the regulations.The simulation results demonstrated the safety of the construction process and provided reference for similar construction analyses.
