  <dc:description>This paper presents the predicted regression equation for the study parameters of Reinforced Concrete (RC) beams strengthened with Hybrid Fibre Reinforced Polymer (HyFRP) laminate at the soffit of beam. To study the effectiveness of HyFRP laminate on flexural strengthening a total of five beams were cast and tested.The variable parameters are thickness, elastic modulus and tensile strength of HyFRP laminates. Four combinations of HyFRP laminates precisely, 90% Glass fibre + 10% Basalt fibre of thickness, 80% Glass fibre + 20% Basalt fibre, 70% Glass fibre + 30% Basalt fibre, 60% Glass fibre + 40% Basalt fibre, and their corresponding thickness were 2.78, 3.24, 3.86 and 4.24mm respectively.The test results concluded that reinforced concrete beams strengthened with 70%Glass + 30%Basalt HyFRP laminate enhance the ultimate load carrying capacity of 68.97% with respect to control beam. The values reached through the predicted regression equation showed equitable accuracy with those of experimental values.</dc:description>
