Over the past two decades Fiber-Reinforced Polymer (FRP) composites has gained acceptance in civil engineering industry as a result of the urgent need to retrofit exiting constructed facilities and structures. This book focuses on the shear strengthening of reinforced concrete (RC) beams using FRP composites. Several research problems related to shear strengthening still linger and therefore require further research studies to be entirely solved. The main objective of this book is to experimentally and analytically study the FRP strengthening methods of full-scale RC beams in shear.
