Abstract
Cast-in-place and precast construction must consider a possible fracture of concrete along the reinforced joint. Moreover, the joint quality significantly affects its strength properties. The stress-strain state of the joint can be divided into three classical stages.It is shown that the stress-strain state of cast-in-place and precast construction under a shear load, is characterized by the linear dependence between the maximum shear stress, vertical compression of the joint, and transverse reinforcement. Since the joint deformation relates to friction and adhesion, the Deryagin binomial law of friction is used to determine the bearing capacity identification of the reinforced joint.The proposed calculation method implies the ultimate shear stress as an exhaustion criterion for the bearing capacity, which based on the true friction coefficient, compression stress and yield strength in the transverse reinforcement. It is shown that the obtained results are in good agreement with the experimental data.
