Experimental study on the failure and deformation of beam-column joints under seismic loads
Abstract
Beam-column joints play an important role, affecting the earthquake response of reinforced concrete (RC) frames. Their behavior is influenced by the way in which they damage the beams, columns and the complex interaction between the shear, bonding and confined mechanisms in a limited zone. To clarify the force-bearing and deformation of the joints that are being designed under earthquake loading and will be available in Vietnam, experimental studies are conducted in 1:1 scale specimens. This paper introduces the results of experimental research on the failure and deformation of the joints, as well as the causes of these behaviors.
Keywords: Beam-column joint, seismic experiments, earthquake, reinforced concrete (RC).
