    Standard compression tests are conducted on concrete cylinders made with concrete having different amount of steel fibres to investigate compression behaviour of steel fibre reinforced concrete. The effect of volumetric ratio of steel fibres on compressive strength, corresponding peak strain and the compressive stress-strain curve is explored. The test results show that the more the amount of fibres the higher the compressive strain the cylinder can sustain. It is also observed that both compressive strength and the strain corresponding to the peak stress increase with the addition of steel fibres. Interrelationships relating the compressive strength and the corresponding peak strain with the volumetric ratio of steel fibres are established based on the test results. The experimental result also shows that if the compressive stress and strain are normalized with respect to the compressive strength and the peak strain respectively, the resulting normalized stress-strain curves lie close to each other and are not influenced by the fibre content. An equation to represent this unique relationship between the normalized compressive stress and strain is also proposed and verified.
