Strength of Interior Reinforced Concrete Beam-Column Assembles

This paper provides a method to predict the strength of interior reinforced concrete beam-column joints that fail in shear before the plastic hinges occur at both ends of the adjacent beams. The proposed method takes into account the axial force ratio, the compressive strength of concrete, and the shear strength deterioration in the beam-column joints. In order to verify the shear strength of the proposed method, the behaviors of 38 interior beam-column joints were compared. Comparisons between the observed and calculated shear strengths of the tested beam-column assembles, showed reasonable agreement.
