Continuous fiber reinforcing materials(CFRM) are given attension as a new highquality reinforcing orprestressing material for concrete structures. The purpose of this study was to establish design procedures for concrete structures with CFRM.The main results were obtained from the following investigations.1) Variation properties of tensile strength of CFRM of carbon, aramid and glass fibers, neccessary number of specimens to determine the characteristic strength of CFRM, relation between elastic moduli of CFRM and stress levels, bond properties of CFRM, and creep properties of CFRM were investigated.2) Ultimate moment of concrete beams with CFRM main reinforcement, ultimate shear force of beams with CFRM main reinforcement and with or without CFRM shear reinforcement, and ultimate shear force of prestressed concrete beams with CFRM tendon were investigated.3) Minimum main reinforcement of beams with CFRM, and improvement of ductility and capacity of moment redistribution of beams by confinement of concrete with CFRM were investigated.4) Deflection and crack width of beams with CFRM were investigated.5) Prestressed concrete with CFRM external cable, strengthening of damaged reinforced concrete by prestressing with CFRM external cable, and chemically prestressed concrete with CFRM were investigated.
