Abstract

The objective of this research is to provide an overview of the state of the art concerning the structural behavior of concrete beam and column externally reinforced with Fiber Reinforced Polymers (FRP) systems effective to enhance the structural load-carrying capacity. Basalt FRP (BFRP) fabric is a promising material for the application to structure strengthening with its advantages of low cost, corrosion resistant and sound mechanical property, but only limited studies of using Basalt FRP fabric to externally strengthen RC beam and column are available. This study is to experimentally explore the effectiveness of application of UD-Basalt FRP fabric with epoxy to strengthen RC beams under two-point bending test and Columns under axial load. Totally five RC-beams and five RC-columns will be casted which will consist of two control beams and columns and three single BFRP U-warpping beams and fully single layer BFRP warpping columns and result are compared for flexure strength of beam and axial strength of columns with M-40 grade of concrete as per IS 10262-2009.UD Basalt fabric retrofitted with U-warpping pattern improved ultimate load carrying capacity (flexural strength) for beam and ultimate load (axial load) carrying capacity for short column than control specimens.
