ABSTRACT

Abstract The U.S. Navy is studying the use of carbon fiber reinforced plastic (CFRP) as an alternative to replacement with ordinary reinforced and prestressed concrete. CFRP sheets were bonded to under-reinforced concrete beams without shear reinforcement. The CFRP enhanced the bending strength significantly but resulted in a shear failure which reduced the beam ductility. Adding both flexural and shear CFRP reinforcement resulted in a bending failure with enhanced ductility and energy absorption.
