The relationship between joint shear stress level and the limit deformation of a beam-column joint caused by the compression failure of panel concrete was evaluated from the test results of six half-scaled reinforced concrete beam-column joint specimens. And the effect of bond characteristics of beam bars passing through the joint on the limit deformation was also discussed from test results. It was shown that the limit deformation of the beam-column joint became gradually smaller as the joint shear stress level grew high. And when the strain of joint strut concrete reached the strain at the compressive strength of cylinders, the deformation was lager for good bond specimens than that for normal bond specimens. In good bond specimens, the compressive strut was formed widely in a joint, and local stress concentration could be avoided in the joint.
