This paper focuses on the analytical and experimental investigations carried out on the tensile properties of High Strength Steel Fibre Reinforced Concrete (HS-SFRC). The steel fibres used here are circular double-end hooked steel fibres and the grade of concrete used is M60. The High Strength concrete is prepared using Silica Fume and Fly Ash as admixtures, along with a Super Plasticizer. The direct tensile tests have been carried out on specimens with different fibre combinations, viz., 0.5%

The steel fibres were modelled using the geometry module before distributing and orienting them vertically based on the calculated fibre composition along critical failure zones identified within the concrete specimen. The plain concrete specimen was assigned a linear elastic property prior to analysis. Another model with a homogenous material property has also been generated and analysed for tensile loading. The results obtained from analysis were correlated using the experimental results.
