Explain the stress-strain behavior of concrete in RCC.
stress-strain behavior of concrete in RCC.
Reinforced cement concrete (RCC) exhibits a nonlinear relationship in the stress-strain behavior of the concrete. In concrete, strain initially increases proportionately to stress, as per Hooke's Law up to the elastic limit. Concrete experiences tensile stress-induced cracking beyond the elastic range, which causes a nonlinear increase in strain with stress.
When concrete reaches its ultimate compressive strength, it loses its strength and becomes brittle, which can cause a sudden failure. In tension, the stress-strain curve is linear until cracking happens, but in compression, it usually exhibits a parabolic shape. Steel reinforcement improves tensile strength and ductility, which helps RCC perform better under load because steel resists tensile forces while concrete manages compressive forces.
