Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is a versatile building material as it is characterized by very high compressive strengths, ductile tensile characteristics, ductility and energy absorption. However this material is not widely used due to a lack of understanding of the structural behaviour and mechanism unlike normal reinforced concrete. Therefore this study aims to study experimentally the behaviour of UHPFRC columns and beams that are tested under axial compression and eccentric compression with varying load eccentricities; both short and slender columns are investigated so that the complete axial load-moment interaction envelopes can be generated and the behaviour can be compared. The interaction diagrams are also generated analytically by modifying the classical methods for normal RC columns and beams to incorporate the special features of UHPFRC and the analytical results are shown to be in good agreement with the test results.
