What is the difference between anchorage length and development length?

Anchorage length is the required distance to transfer a load and is dependent on the materials used. Development length is the length of the reinforcement bar or rod required to transfer the load safely to another bar.

What is anchorage of reinforcement?

Anchorage of reinforcement refers to the mechanism by which reinforcing bars (rebar) are securely embedded in concrete to ensure effective load transfer between the concrete and the steel. Proper anchorage is crucial for the structural integrity of reinforced concrete elements, as it prevents the bars from pulling out under tension. It typically involves extending the rebar beyond the concrete section or using hooks and bends to enhance grip. Adequate anchorage ensures that the reinforcement performs its intended function in resisting tensile and shear forces.
