This paper deals with an experimental and analytical study to simulate partial-interaction behavior by using push-out results for steel-concrete composite members. In order to analyze the interface behavior of steel-concrete by the degree of interaction, a total of 9 push-out test specimens were tested. The steel-concrete interface was idealized by a number of interface elements and the properties of interface element were determined as the results of push-out tests. To validate the current study, using a commercial structural analysis program, a nonlinear structural analysis was performed for a steel-concrete composite member exclusively designed for this study, and the results were compared with the results of the flexural test. The results of this study have shown that the partial-interaction behavior of steel-concrete composite members can be efficiently and accurately predicted by the analysis method presented in this paper.
