    This implies that the at the overreinforced construction joints is governed by the crushing of the concrete before the transverse reinforcement reaches its yield strength. Hence, needs to be limited to certain value in order to avoid the overestimation of the shear transfer of transverse reinforcement due to the precrushing failure of concrete.
