Abstract:
Monotonic tests on beam-column joints show that failure of the connection can either be in the beam (bending failure) or inside the joint (shear and bond failures). The behavior of exterior beam-column joints is different from that of interior connections. The parameters influencing the shear strength are investigated using the authors’ tests on exterior and interior connections as well as tests from the literature. A model is developed to predict the failure load and the failure mode for exterior and interior beam-column joints. The model has been calibrated using a database with more than 200 static loaded tests. The proposed model accounts for the main parameters influencing the shear strength of exterior beam-column connections such as the joint slenderness, the column reinforcement ratio, the compressive concrete strength, the efficiency of the beam reinforcement anchorage, and the amount, as well as the efficiency of, the shear reinforcement. For interior beam-column joints, the main factor affecting the shear strength is the concrete compressive strength.
