RAM Concept shows shear reinforcement zones on plan with the following parameters:

• number of spaces in the zone
• number of legs per shear reinforcement set
• spacing of the sets
• length of the zone

The following figure shows shear reinforcement.

For US units and bar size, the zone is 2.78 ft. long and has 4 spaces with two #4 legs @ 8.34” centers.

For metric units and bar size, the zone is 0.772 m long and has 4 spaces with two 12 mm legs @ 193” centers.

For both unit systems, there are five shear reinforcement sets (spaces + 1).
