Research on Design and Calculation of Bridge Cantilever Prestress

This paper studies the automatic flow of bridge cantilever prestress design and calculation. The research shows that the automated flow can be divided into the coordinate calculation of the box girder section, the coordinate calculation of the reinforcement configuration, the 3D model establishment of the box beam and the reinforcement configuration, and the generation of ABI prestress Analyze the input files, pre-stress analysis and post-processing check operation, and drawing of the construction drawing of each node section, in order to provide reference for the bridge cantilever pre-stress design.
