Tensile Properties of GFRP Bars after Exposure to Harsh Laboratory and Field Environmental Conditions Saleh Alsayeda, Tarek Almusallam b, Yousef Al-Salloumc and Sherif El-Gamal d Department of Civil Engineering, College of Engineering, King Saud University, P.O.
Introduction Due to their light-weight, high strength, and corrosion resistance, FRPs have been widely used for civil infrastructures throughout the world for the last fifteen years.
Among different types of FRPs, glass FRP (GFRP) bars have drawn more attention in civil engineering applications due to their low cost com-pared to other types of FRPs [1].
