Seismic resistance of reinforced concrete beam-column joints
Six of specimens tested represented exterior joint unconfined by spandrel beams; seventh specimen had short unloaded spandrels on each side of joint; test variables were column size, column axial load, and amount of joint lateral reinforcement; reversible elastic and plastic load cycles were applied to each specimen to simulate earthquake loads; closed rectangular hoops surrounding joint were shown to be essential in developing ductility and maintaining strength of isolated joints in structural frames; energy absorption required in building frames subjected to earthquakes was demonstrated to be amply provided by properly designed reinforced concrete frame.
