Abstract
To ensure the safety of the steel box girder steel pipe,it is necessary to fully understand the mechanical and deformation behaviour of the steel pipe.Finite element theory and software provide a foundation for simulation analysis and optimization design of steel box girder steel pipes.This study calculates and analyzes the axial force,tensile and compressive stress,and displacement of the steel box girder steel pipe bracket system.Simulated loads were applied to the bracket system,and the settlement and strain at each measurement point were recorded to verify the safety of the bracket system and the reliability of the numerical calculations.The results show that both the maximum stress and displacement of the bracket are within the strength limits of the steel pipe,and the stiffness and stability of the bracket system meet construction requirements.The Midas finite element program is suitable for numerical simulation of the steel pipe system.
