Effect on flexure properties of beam on hybridisation by glass fibre reinforced polymer bars.

Fibre Reinforced Polymer has been used to eliminate deterioration of steel from corrosion, cost effectively and to make it available for all structural uses. This paper will give a review on effective type of FRP bar among Glass, Basalt, Carbon, Aramid Fibre Reinforced Polymer bars in terms of ductility, flexural performance and cost. In the study it has been found that many polymers have been used to strengthen the RC structure in various orientation of polymers for their respective strengthening criteria like moment capacity, shear capacity as they are light in weight, high tensile strength, anti-corrosive & non-magnetic. The main disadvantage of FRP bar is its brittleness. Hence, hybrid FRP bars are introduced to improve its ductility and flexure performance. Among all the polymers GFRP was cost effective, easily available and a material with required structural qualities which can replace steel partially. GFRP was used in many forms like bars, fabric sheets etc., based on the requirement and ability to develop a bond & ease of placing. However, steel could not be replaced totally but there was significant increase in strength and ductility when GFRP was used. From the study, it was concluded that the arrangement of GFRP bars shall be placed around the corners so as to enhance ductility and to avoid corrosion [ABSTRACT FROM AUTHOR]
