This Research article illustrates Effects of cracks and optimization on the strengthening of HSC beam with the addition of hybrid FRP laminates under the flexural type of loading. This current research work intends to study how alternative sequences of carbon FRP (CFRP) and glass FRP (GFRP) laminates with the combinations of hybrid FRPs effect the enhancement of the reinforced cement concrete beams. For this research investigation, 17 rectangular beams were cast and prepared using Glass FRP and Carbon FRP. Out of the casted beam, one beam aided as a control concrete beam and the remaining 16 beam were supported by the use of hybrid Fibre Reinforced Polymer laminates in the form of glass and carbon. Concrete with reinforcements after laminating beams with two, three, and even four layers of HyFRP and a static type of load was given to the beam until they failed. The initial and progressive fractures of HSC beam, as well as beam failure both without and with hybrid FRP laminates were investigated and analysed. Comparisons and presentations of analytical and experimental data were done with the intention of deriving new findings. The conclusions of the tests lead one to the assumption that the consequences of hybrid FRPs on the cracks and ductility of High Strength Concrete beams are strengthened differently depending on the order of the FRP layers.
