reinforced concrete subjected to restraint forces

Stress Transfer Across Interfaces in Reinforced Concrete

because of the variable restraint stiffness provided by the reinforcement crossing the crack and the crossed by a reinforcing bar and subjected to shear force V, due to which a relative shear displacement, b, results. Overriding brought about by crack in reinforced concrete differs from that of plain concrete. This is due to the steel
