About this detail

This structural detail outlines requirements for reinforcing bar splices and development lengths within concrete members, including staggered couplers and welded splices. It details non-contact lap splices requiring a maximum spacing of six inches or one-fifth of the lap length, alongside contact lap splices tied with wire ties and maintaining a minimum six-inch offset. Clear spacing criteria between bars are established based on bar diameter and aggregate size, applying development length modifiers when more than twelve inches of fresh concrete is cast below the horizontal bar. Hook dimensions and critical surface locations are also specified.
