Ductility is a structural design requirement

Ductility is a structural design requirement in most design codes. In steel reinforced concrete (RC) structures, ductility is defined as the ratio of post-yield deformation to yield deformation which usually comes from steel yield. Properly reinforced and dimensioned concrete members exhibit a good ductile behavior.

Ductility is the ability of a material to be drawn or plastically deformed without fracture. It is therefore an indication of how ‘soft’ or malleable the material is. The ductility of steels varies depending on the types and levels of alloying elements present.

Ductility is key to good seismic performance of structures.

Ductility Ratio plays vital role in design.
