Abstract: Fiber Reinforced Polymers (FRPs) are one the most innovative materials for strengthening and retrofitting structures and structural elements due to their high modulus of elasticity, light weight, and other valuable properties. FRPs are often used in reinforced concrete, since concrete has a low modulus of elasticity and is more susceptible to exhibit cracks and brittle behavior. However, FRPs are not frequently used to repair steel structures because they are more ductile and have a relative high modulus of elasticity compared to concrete. In this work, a literature review for retrofitting structures using FRPs is presented. It is divided into two principal categories, concrete structures and steel structures. The review shows that there is a vast collection of information on strengthening and retrofitting concrete elements with FRPs. The results show that using FRPs in certain concrete elements provides increasing ductility and shear capacity of a structure leading to a favorable seismic behavior. There is also valuable information for strengthening concrete structures that are susceptible to blast loads. When compared to reinforced concrete, the applications and available research on strengthening steel elements with FRPs is limited. Specific FRP applications that are being developed are discussed in this report.
