Abstract: • 14 SS-UHPC columns were test under monotonic or cyclic axial loading. • The failure mode and performance indexes SS-UHPC columns were analyzed. • The confinement effect of SS-UHPC columns were discussed and analyzed. • A novel design formula was proposed to predict the axial capacity of SS-UHPC columns. A novel type of composite column consisting of an ultra-high performance concrete core confined by a stainless steel tube (SS + UHPC column) was investigated. The system is characterized by excellent corrosion resistance, aesthetic appearance, high axial capacity and pronounced ductility. An experimental programme comprising 14 SS + UHPC stub columns was carried out, covering both monotonic and cyclic loading. The main parameters varied in the experiments were the column diameter, the tube thickness and the loading scheme (monotonic or cyclic). The resulting load-displacement curves, failure modes, strain characteristics, axial capacities, confining pressures, stiffness degradation and ductility indices were thoroughly analyzed. The applicability of current empirical formulae in predicting the confined strength of UHPC in SS + UHPC columns was also examined, and found to be inadequate. Therefore, a new equation linking the confining pressure to the confined strength of UHPC was developed. Based on this, a design equation to quantify the axial capacity of SS + UHPC columns was presented. [ABSTRACT FROM AUTHOR]
