Ten reinforced concrete beam-column joint specimens subjected to repeated reversible seismic loading were studied. The parameter of this test is various reinforcement devices in joint panels for improving earthquake-resistant capacity. For example, in one specimen, longitudinal bars of beams going through the joint were welded to stirrups set in the joint, while in another specimen, longitudinal bars of beams in the portion of column width were subjected to induction heat-treatment to prevent yielding. Another parameter is column width, load-deflection characeristics, energy-absorbing capacities and pullout of beam reinforcement from joint were compared. Further, deformation mechanism of beam end hinges was studied.
