Experiment plays an important role in studying the mechanical performance of structures in civil engineering. But it takes a lot of time and costs expensively. Numerical model is a good option to simulate the test results. It is also convenient to carry out parameter analysis. This paper introduced the entire process of a numerical simulation of steel-concrete composite deck test. The mechanism of interfacial behavior is analyzed. Simulation method of interface is introduced specifically. The results show that the proposed method of interfacial simulation is applicable. The results of simulation and test agree well with each other. The slip is nonlinear with load. It releases the interfacial connection and enlarges the deflection of composite deck. The uplift is quite small compared with slip so that it can be neglected when evaluating the structure behavior of composite deck.
