When the framed structures are subjected to horizonal load, such as earthquake loading, the bending moment distribution of composite beams changes from positive and to negative at the point of inflection. In this paper, the repeated elastic-plastic behavior of composite beams subjected to both positive and negative moment is examined experimentally. The test specimens are H-shaped subassemblage composed of two vertical columns and horizontal composite beam. The bending strength of column is greater than that of composite beam. The experimental work of this investigation consists of testing three composite beams with 5 cm, 7 cm and 9 cm thick concrete slab and one steel beam without concrete slab. Each steel beam and columns of specimens are the same section. Further, pushout tests are carried out for the purpose of evaluating shear strength of stud connector. The results of four tests are examined and compared with theoretical predictions.
