About this detail

A concrete beam and girder construction joint is positioned within the middle one-third of the span between a first pour and a second pour. All reinforcing steel continues uninterrupted across the joint interface. Additional ties are spaced at three inches typical near the joint, with one-foot spacing typical away from the joint. Reinforcement sizing varies by member width, utilizing one number six bar each way for members up to seven inches wide, two number six bars each way for members eight to twenty inches wide, four number six bars each way for members twenty to forty inches wide, and six number six bars each way for members wider than forty inches.
