18.104.22.168 Stiffening effect of concrete in tension area
Stiffening effect of concrete in tension area
In cracked parts of the reinforced concrete, the tensile forces in the crack are resisted by the reinforcement alone. Between two cracks, however, tension stresses are transferred to the concrete through the (displaceable) bond. Thus, the concrete contributes to the resistance of internal tension forces, which leads to an increased stiffness of the component. This effect refers to the stiffening contribution of the concrete in tension between the cracks and is also called tension stiffening.
