What is Bond, Bond stress, Anchorage length & bond, Development

Bond: A mix between steel and concrete creates a bond. A Perfect bond generates in such a way that no slips can occur between concrete and steel. Which transfer load from steel to concrete and vice versa.

Bond stress: stress developed on the outer surface of steel or reinforcement surrounding concrete is called bond stress. It helps to resist every force which tries to do a part between the bond of steel and concrete. Bond stress may vary as the grade of concrete varies.

Anchorage length & bond: anchorage bond is shown when the other certain forces are removed from that bar.  So it will become necessary to transfer this load from the bar to its surrounding concrete at a certain length. Then this length is called anchorage length.

Development length: A length that is required to transfer the force in a bar to the surrounding concrete through their bond is called development length. It can be measured by the pull of the test.
