Girder Erection (Partial) [CUG]

If the construction of girders and cross frames needs to be divided into multiple stages, this component can be utilized. However, during the typical design process of steel I-girder bridges, a detailed analysis of the erection sequence for girders and cross frames is usually not necessary. Engineers who are responsible for girder erection typically conduct this detailed analysis after the design process.

Girder Erection

Stage: Choose the stage in which you intend to construct the girders ,cross frames and lateral bracings.

Girders: Choose the girders for erection.

Girder Start Station: Entering the relevant stations, such as the splice point or girder start station, can be used to erect the girder in multiple steps.

Girder End Station: Entering the relevant stations, such as the splice point or girder end station, can be used to erect the girder in multiple steps.

Cross Frames: Choose the cross frames for erection.

Lateral Bracings: Choose the lateral bracings for erection.

Splice Load [Ignore/Include]: If splice weight loads are to be included in the FEA, set the option to ‘Include’ for this parameter. If the option ‘Ignore’ is selected, the weight loads of the splices will be neglected.

Stiffeners/Gusset Plate Load [Ignore/Include]: If the weight loads of the stiffeners or gusset plates are to be included in the FEA, select ‘Include’ for this parameter. If you need to neglect the weight loads of the stiffeners or gusset plates, select ‘Ignore’.

Girder Self-Weight Factor: The Girder Self-Weight Factor is a parameter used to adjust the contribution of a girder's own weight to the overall structural load calculations. This factor allows for the scaling or modification of the girder's self-weight in finite element analysis (FEA).
