# Bent Cap \[CBG]

## Integral Bent

**Box Girder:** Specify the Box Girder to be used for generating the Bent Cap.

**Support Line:** Select a support line to define the location of the Bent Cap.

**Thickness:** Specify the thickness of the Bent Cap.

**Material:** Assign a material to the Bent Cap. You can either import a material or use a previously defined one.

**Compute Bent Length from Deck Edge \[YES/NO]:** When YES, the bent length is automatically computed from the deck edge geometry; when NO, the user-entered **Bent Length** is used.

**Bent Length:** Total length of the bent cap along the transverse direction. Used when **Compute Bent Length from Deck Edge** is NO.

**Transverse Offset:** Offset of the bent cap from the supporting centerline in the transverse direction.
