Abstract

The empirical models for predicting the shear strength of concentric and eccentric reinforced concrete exterior beam-column joints and the interior joints are developed. To propose the empirical model, different parameters affecting the shear strength of reinforced concrete beam-column joints under reversed cyclic loads have been evaluated and identified. The identified parameters, namely, concrete compressive strength, beam and column longitudinal reinforcement, beam-column depth ratio, column axial load, eccentricity, and joint shear reinforcement, are considered in this study. The effect of the aforementioned parameters is determined from the statistical evaluation of the database consisting of specimens collected from the literature, including a large amount of results of the exterior and interior beam-column joints with the parameters mentioned above. The effectiveness of the proposed model is verified by comparing the predicted shear strength values of the proposed model with three design codes of practice. The results indicate that the shear strengths of the reinforced concrete beam-column joints predicted by the proposed model are more accurate than those predicted by other considered codes. The proposed empirical model is simple in use and can be used for the seismic design purpose to prevent premature shear failure of beam-column joints.
