Deck Deconstruction

For rehabilitation projects, after constructing the existing structure, users can deconstruct some portions of the deck. The OpenBrIM FEA engine will automatically calculate load distribution among the girders based on stiffness and the unbalanced load vector following deconstruction.

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

Deck: Choose the deck to define the deconstruction

Start - End Skew [deg]: The start skew and end skew parameters are utilized to define the deck boundaries for deconstruction. This parameter is also involved in creating the mesh, so entering an incorrect value may result in improper mesh generation.

Longitudinal

Start -End Station: Stations are positioned along the PGL in the longitudinal direction. The start skew and end station parameters are utilized to define the deck boundaries for deconstruction. This parameter is also involved in creating the mesh, so entering an incorrect value may result in improper mesh generation.

Transverse

Transverse Const. Type[Complete/Partial]: Choose the "Complete" option if the entire deck between two longitudinal stations is removed. Select "Partial" if only the right or left portion of the deck in the transverse direction is removed.

Left-Right Offset Start [PGL] - Left-Right Offset End[PGL]: These parameters apply only when the "Partial" option is selected. Enter the transverse offset along the PGL at the start/end longitudinal station. "Right" is used to define the right boundary when looking up-station along the alignment, while "Left" refers to the opposite side.
