Girder and Bracing Deconstruction [STG]

Girder Deconstruction

For rehabilitation projects, after constructing the existing structure, users can remove some parts of the girder. The OpenBrIM FEA engine automatically calculates load distribution to the bearings based on stiffness and the unbalanced load vector after deconstruction.

Stage: In this stage, the girder's analytical model will be deconstructed, and the unbalanced load vector will be computed and redistributed throughout the structure.

Girders: Choose the girders for the deconstruction.

Girder Start Station: This parameter specifies the starting station of the girder along the PGL in the longitudinal direction. [Length]

Girder End Station: This parameter defines the ending station of the girder along the PGL in the longitudinal direction. [Length]

Internal Cross Frames: Choose the cross-frames for the deconstruction.

The following objects are available for selection in the project:
