Test specimens consisting of a steel column stub and composite steel-concrete beam are tested under cyclic loading. The results show that composite beams subjected to cyclic loading exhibit stable hysteresis loops and good ductility. The behavior under negative moment is governed by the local buckling of beam flanges and web. Beams with horizontal web stiffeners or stocky webs show marked increase in ultimate strength and ductility under negative moment.
