DUCTILITY REQUIREMENTS FOR BUILDINGS
www.sefindia.orgthe brittle failure as result of inelastic deformation can be avoided only if the concrete is made to behave in a ductile manner so that the member can absorb and dissipate large amount of energy. Hence in the case of reinforced concrete members subjected to inelastic deformation, not only strength but also ductility plays vital role in the design.
