In order to analyze the section stress considering the slip effect on the interface between concrete and steel, models for calculating global moment, local moment, elastic stress, and yield moment on composite steel-concrete beam section are created. These models are based on the assumption that section moment consists of global moment and local moment. Formulas to calculate the elastic stress and yield moment of composite beams are deduced. Comparison with test results shows that the calculation results of the yield moment on the sections are a little smaller than the test results and with good accuracy. The models provide a reliable method to calculate the beam section stress and yield moment.
