Collecting available 332 test data, the database of interior beam -column joints was constructed. In this paper, analyzing the previous test specimens, which were failed in joint shear before beam hinging, the joint shear strength was examined. Following findings were obtained : (1) Joint shear strength was greatly influenced by concrete ,strength [σ_B]. However, axial column compressive stress level and joint shear reinforcement ratio were not major factors for joint shear strength. (2) Joint shear strength [_cτ_p] was evaluated to be proportional to σ_B^<0.712>^. (3) Specimen size and shape does not affect significantly on joint shear strength. (4) Shear failure in joint before beam hinging can be classified by the ratio of joint shear strength to the joint shear stress at beam flexural capacity [_cτ_p/τ_u] .
