The following is a list of all the possible bar marks that may appear in the output.
A1 | Top corner (flexural reinforcement) |
A2 | Bottom corner (flexural reinforcement) |
A100 | Top slab, inside face transverse (flexural reinforcement) |
A200 | Bottom slab, inside face transverse (flexural reinforcement) |
A300 | Top slab, outside face transverse (flexural reinforcement for multi-cell culverts, temperature steel for single cells) |
A400 | Bottom slab, outside face transverse (flexural reinforcement for multi-cell culverts, temperature steel for single cells) |
B1 | Exterior wall, inside face vertical (flexural reinforcement) |
B2 | Exterior wall, outside face vertical (flexural reinforcement used in combination with A1 and A2 bar if a U-bar is not used) |
C1 | Top slab, bottom slab, and wall longitudinal (temperature reinforcement) |
C100 | Top slab, inside face longitudinal (distribution reinforcement) |
C200 | Bottom slab, inside face longitudinal (distribution reinforcement) |
Reinforcement Types
STR | Straight |
L-BAR | L-shaped |
U-BAR | U-shaped |
Bar sizes range from #4 #3 to #11. Bar spacings range from 2 inches minimum to 12 inches maximum. The program uses the actual reinforcing bar diameter when locating design reinforcement. For mesh, the program supports mesh sizes from 2.5 to 45, in both smooth and deformed types. Mesh can be spaced at 2 inches through 12 inches.

Splice Length Chart
The program will compute and print splice lengths for bar marks B1, B3, C1, C100 and C200 as per AASHTO Specifications. Bar splices for bar marks A100, A200, A300 and A400 will be printed only if the required bar length exceeds 60 feet.
