The fiber Reinforces Polymer as a strengtheninig of Reinforced Concrete

Abstract

Reinforced concrete structures show excellent performance in terms of structural behavior and durability except for those zones that are exposed to severe environmental and mechanical loading. Rehabilitation of deteriorated concrete structures is a heavy burden also from the socio-economic viewpoint since it also leads to significant user costs. The need to repair and strengthen RC buildings and their structural elements occurs when they do not possess sufficient strength, stiffness, and/or ductility due to damage. Fiber Reinforced Polymer composites are widely used to improve the performance of damaged concrete. Using Fiber Reinforced Polymer composites as a tool to repair damaged concrete structures could improve ductility, flexural or shear strength, with minimal increase in size and with rapid installation. The advantages of FRP are also high strength to weight ratio, resistance to corrosion, wear, impact, and fire. The disadvantages of Fiber Reinforced Polymer are the high cost and demand for skilled labor. This paper will evaluate the influence of FRP composites on increasing the capacity of reinforced concrete beams.
