Abstract: The aim of this study is first to develop hybrid fibre reinforced concrete (HFRC) and then to characterize and quantify the benefits obtained by the concept of hybridization. Hybrid composites were cast using two fibres namely Glass and Bamboo of different fibre proportions i.e., 1%, 1.5% and 2% in M35 grade of mix. Compressive test and split tensile strength were performed and results were extensively analyzed to associate with above fiber combinations. The dynamic properties are further analyzed for the optimum percentage of hybrid fibres using ETABS. The reinforced beams of a G+4 residential building is replaced with the optimum dosage of hybrid fibres and analyzed under seismic loads. It is concluded that the overall displacement of the structure is less when compared with conventional reinforced structure
