About this detail

A concrete construction joint is located within the middle third of the beam span between a first pour and a second pour. All reinforcing steel continues uninterrupted across the joint interface. Additional ties are required typically at beams, with diagonal dowels or lap reinforcement configured symmetrically. The joint includes a keyed notch profile with a 1 1/2 inch offset. Specific reinforcement schedules provide one number six bar each way for members up to 7 inches wide, two number six bars each way for members 8 to 20 inches wide, four number six bars each way for members 20 to 40 inches wide, and six number six bars each way for members wider than 40 inches, with number six bars at 12 inches each way typical for mat footings.
