In order to study the behavior of Steel-concrete composite beams with different shear connection degrees, using finite element software ABAQUS, four models with different numbers of headed studs are established, all of which apply appropriate concrete and steel constitutive models, and contact relationship. The accuracy of finite element models is verified by comparing the simulation results with corresponding beam tests in multiple aspects, for instance, the interface slip, the ultimate capacity, the failure modes and the load-strain distribution. The analysis focuses on the interface slip development of composite beams with different connection degrees, and the results show that the interface slip seldom becomes the control condition when designing composite beams. A further parametric study is performed to investigate the effect of various parameters on the static response of composite beams. Finally, the applicable conditions and limitations of different modeling methods are discussed. The modeling method used in this paper is suitable for simulating the static performance of composite beams, especially in the investigation of the interface slip development.
