Most commonly the reinforced concrete structures fail by exhibiting the flexural and shear pattern of cracks. So in order to avoid this type of failure and to increase the life span of the structure, the strengthening of the structural members has to be studied. The concept of using fibres in the concrete has more advantage in increasing the concrete strength. However, in this investigation two different types of fibre which has higher (Steel hooked end fibre) and lesser moduli (Polypropelene fibre) which increases the modulus of elasticity of concrete. This Hybrid combination of fibres will reduce the chances of brittleness and small crack formation in the concrete. The use of computer software to model these elements is much faster, and extremely cost-effective. Hence, the Non-linear Finite Element Analysis (FEA) of a Hybrid fibre reinforced concrete beams has been modelled and analysed using the ANSYS software package. The flexure and shear pattern of arrangements in control beam and three Hybrid fibre Reinforced concrete beams of different proportions (1%, 1.5% and 2%) were modeled and analyzed for the results of ultimate load, deflection and stiffness ratio of the beams.
