A steel-concrete composite fiber beam model is presented in this paper. The composite fiber beam model is made up of a preprocessor program that used to divide composite section into fibers and a group of uniaxial hysteretic material constitutive model based on user defined subprogram UMAT provided by ABAQUS. The steel-concrete composite fiber beam model is suitable for global elasto-plastic analysis of composite frame which is full connection subjected to the combined action of gravity and cyclic lateral loads. The model is verified by a large number of experiments and the results show that the composite fiber model developed by authors possesses better accuracy and broad applicability compared with traditional finite element model. Although the fiber beam model neglects the slip between steel beam and concrete slab, there are almost no effects on global calculation results of steel-concrete composite frames. Simple modeling procedures, high calculation efficiency and great advantage are obtained when analyze composite frames subjected to cyclic loading due to earthquake when used the steel-concrete fiber beam model proposed by this paper.
