Cellular ( web openings ) is a cross-sectional form of reasonable beam , bending stiffness, high carrying capacity, economic construction of the new steel structure . Structure of the class present, China mainly in the capacity and stability problems in the analysis of hysteretic little studied . In this paper, have been studied based on the finite element software ANSYS cellular beams under cyclic loading hysteretic behavior and failure modes to give a systematic study of the following major elements : ( 1 ) describes the process of making a cellular beams and similar ratio obtained through various physical models and prototypes relationship . ( 2 ) for cross- height ratio D = 10,12,14,16,18 hole castellated beams at low cyclic span concentrated load , cross within two concentrated loads , uniform loads across the whole of the system under study , and discuss the different cross- height ratio of the hole cellular beams under three loading hysteresis curves and skeleton curves . Through the initial stiffness index , capacity indicators , displacement ductility index , the energy dissipation coefficient index analysis, obtained when the cross- height ratio D = 14 , the most full hysteresis curve , ductility and energy dissipation factor maximum , with good energy dissipation capacity , as well as with cross- height ratio increases, the hole castellated beams carrying capacity and initial stiffness decreases. ( 3 ) for cross- height ratio of the hole D = 10,12,14,16,18 low cyclic cellular beams span concentrated load , within two concentrated loads across the whole cross- uniform loads Von Mises stress distribution under study discusses the different cross- height ratio and the different forms of cellular beam load failure mode , get cross- height ratio D is equal to 14 in the hole castellated beams under cyclic loading of the force as well as the best performance of each hole castellated beams hole edge stress concentration occurs at the edges by the hole caused by the beam plastic hinge damage .
