Simulation and Mechanical Analysis of Large-Span Steel Truss Lifting Construction Process
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.
