- Anchorage length is the length of a reinforcement required to develop the entire bond, and the bond is measured by bond stress. End anchorage is the length of reinforcement that needs to be embedded into the support for complete stress transfer to maintain the structure’s integrity and thereby enable it to carry the loads1. The length of the anchor and the length of the lap varies according to the areas of tension and stress and depends on the grade of concrete, the size of the rebar, the concrete cover, etc.2. Compression anchorage length is 32 times bar diameter, and tension anchorage length is 40 times bar diameter3.
