The paper presents an experimental study on the performance of steel-reinforced concrete (SRC) joints under reversal cyclic loads. Five composite joint specimens comprising built-up steel-reinforced concrete column connecting to reinforced concrete (RC) beams were tested to failure. Three modes of failure were observed. They are (1) bending failure in beam. (2) bending-shear failure in beam and (3) shear failure in beam and joint. Test results indicated that energy absorption capacity of the SRC joint depends on the modes of failure as well as the levels of axial load imposed on the column. The latter also influence the shear capacity of the joint.
