With sufficient concrete cover, a multi-axial stress state develops in the concrete surrounding the reinforcing bar at both sides of the cracked interface. After increasing interface displacement, the concrete plasticizes […]
EK537
The splitting resistance of concrete can be enhanced if confinement stresses are superimposed onto the tensile ring stresses around the reinforcing bar.
EK536
The angle at which the steel rib bears on the concrete changes as load acting on the reinforcing bar increases.
EK529
The effect of chemical adhesion is small, and friction does not occur until there is slip between the reinforcing bar and the concrete.
