Q. Explain Tension and compression anchorage length?

Tension anchorage length vs. compression anchorage length

Tension anchorage length of steel reinforcement in concrete relies on bond strength. When steel reinforcement is anchored to concrete and is subjected to compressive forces, resistance is provided by the bond strength between steel and concrete and bearing pressure at the reinforcement end. Tension lap length is usually longer than compression lap length. In some design codes, in place of permitting the use of bearing pressure at reinforcement ends, the permissible ultimate bond stress is increased when calculating compression anchorage length.
