This textbook establishes the art and science of strengthening design of reinforced concrete with FRP beyond the abstract nature of the design guidelines. It addresses material characterization, flexural strengthening of beams and slabs, shear strengthening of beams, and confinement strengthening of columns. It discusses the installation and inspection of FRP as externally bonded or near-surface-mounted composite systems for concrete members. It provides innovative design aids based on ACI 440 code provisions, end-of-chapter questions, references for further study, and a solutions manual with qualifying course adoption.
