Stage: Choose the stage on which the selected insertion points or bearings will be constructed. Bearings should be constructed in the same stage as the related girders. If they are constructed prior to the girder construction stage, instability may occur, leading to failed finite element analysis (FEA). Conversely, if bearings are constructed after the girders, it may result in inaccurate FEA results.
Insertion Points: Choose the insertion points that represent the bearings. The selected insertion points are where the bearings will be constructed and connected to the superstructure.
