The influences of a column axial load and a beam bar bond within a joint on the shear strength in reinforced concrete interior beam-column joints were studied. The decrease in the lever arm length at a beam critical section, which was caused by the beam bar bond deterioration within a joint, resulted in the decay of the story shear. The compressive collapse of the diagonal concrete strut developed in the joint panel. The diagonal joint shear however could be carried by the surrounding concrete of the diagonal strut failed by the compression.
