This study investigates the uniaxial tensile strength capacity of High Strength Concrete (HSC) and Steel Fibre High Strength Concrete (SFHSC) using the direct tensile testing method developed at the University of Wollongong. The SFHSC mix contained 1% (by volume) brass coated steel fibres. Steel claws were embedded in the ends of 100 x 100 x 500 mm HSC and SFHSC specimens to prevent slippage and fracture at the ends of the specimens. Steel universal joints were also used to ensure a perfect alignment of the specimens. The cross-sectional area of the tested specimens was reduced in the middle to ensure that failure would occur in the middle. The results indicated that the direct tensile strengths of the HSC and SFHSC specimens were less than splitting and flexure strengths. The direct tensile strength of SFHSC specimens was found to be 20% higher than the direct tensile strength of the HSC specimens.
