Abstract: 
In this study, direct shear tests of HPFRC - steel plate composite elements are conducted so as to evaluate shear stress – relative displacement curves of the interfaces. Besides three-point loading experiments of the HPFRC - steel plate composite beams were conducted. In those experiments, kinds of resigns and shear keys and its combinations applied in the interface are chosen as parameters. In this paper, how the interface affects the mechanical behaviour of the composite elements and beams is discussed. Furthermore, Finite Element Analyses, in which the shear stress – relative displacement curves found in the direct shear tests were installed, are performed to examine the failure mechanism of the composite beams. The paper describes that the ultimate load of the HPFRC and the steel plate composite beams is determined by interface failure and the FE analysis can predict the behaviour reasonably.
