Abstract

This paper presents the behavior characteristics of steel-concrete interface and analysis method to simulate interface behavior by using push-out results for steel-concrete composite members. In order to analyze the partial-interaction behavior of steel-conc rete interface, the interface is idealized by a number of interface elements. A total of 9 push-out specimens were tested and the test results were utilized to provide the properties of interface element in the analysis. To validate the present study, using a commercial structural analysis program, nonlinear structural analysis were performed for the push-out specimens, and the results of analysis were compared with the test data. The results of this study have shown that the nonlinear, slip-softening, as well as linear-elastic behaviors of steel-concrete interface can be efficiently and accurately simulated by the method of analysis presented in this paper.
