Abstract

Three types of interface models for concrete-steel interaction in concrete-filled steel tube (CFST) were quantitatively and qualitatively investigated using published test results. The study is part of the development of a coupled rigid body spring model (RBSM) and shell finite element method (FEM) aimed at modeling CFST and similar concrete-steel composites by utilizing the suitable numerical method for each material, i.e., RBSM for concrete and shell FEM for steel tube. The results of the investigation were discussed and the most appropriate interface model was selected.
