Lapping and Anchorage

For anchorage, the required development length depends on the rebar diameter, bond strength, and stress level, with adjustments for concrete cover, transverse reinforcement, and bar surface conditions (e.g., plain or deformed). Hooks or bends may be used to reduce anchorage length where space is limited.

For lapping, the code requires the lap length to be sufficient to transfer stress from one bar to another, depending on factors such as bar diameter, concrete strength, type of stress (tension or compression), and bond conditions.
