Abstract

Abstract

Concrete-filled stainless steel tubular columns show excellent prospects for application in corrosive environments such as harbor engineering and marine engineering. To further develop the performance of such structures, a composite structure, i. e. steel-reinforced ultra-high performance concrete-filled stainless steel tubular column was proposed in this paper. Meanwhile, six short and eight medium-length column specimens were designed and fabricated with the parameters of diameter to thickness ratio, length to diameter ratio, steel profile content ratios, etc. Axial compression experiments and finite element analysis were executed to investigate the failure mode and failure mechanism of the specimens, as well as the influence of relevant parameters on the mechanical performance of the specimens. The results showed that the bearing capacity and ductility of the specimens increased with the decreasing of the diameter to thickness ratios and length to diameter ratios, and increased with the increding of the steel profile content ratios and strength of the pre-embedded steel profile; the ductility of the specimen decreased with the increase in core concrete strength, but the bearing capacity was the opposite. Based on the experimental and finite element results, a prediction model for the bearing capacity of steel-reinforced ultra-high performance concrete-filled stainless steel tubular was proposed, providing a reference for the engineering application of such structures.
