Because fibers made of such materials as glass, carbon, aramid, and vinylon have very high resistance to corrosion, more attempts are being made to utilize continuous fiber reinforcing materials (CFRM) in reinforced and prestressed concrete structures instead of ordinary steel. However, CFRM are composite materials composed of millions of fibers and binding material, and have little plastic behavior. The mechanical behavior of reinforced concrete using CFRM is quite different from conventional reinforced concrete. As of the present, there is no general agreement relating to the methodology to be adopted in design or testing methods of such fibers. Realizing this problem, the Concrete Committee of the Japan Society of Civil Engineers (JSCE) organized a subcommittee on CFRM in 1989. The following results have been published as the committee report in 1992: design concept for concrete members using CFRM; test methods for durability of CFRM; concept for durability of CFRM; and a state-of-the-art report on CFRM for concrete structures. Paper describes the design concept for concrete members using CFRM.
