SYNOPSIS
As fiber made of materials like glass, carbon, aramid and vinylon, are very high resistance to corro- sion, more and more attempts are being made to utilize continuous fiber reinforcing materials (CFRM) in reinforced and prestressed concrete structures instead of steel. However, CFRM is a composite material composed of millions of fibers and binding material, and has little plastic behav- ior. The mechanical behavior of reinforced concrete using CFRM is quite different compared to conventional reinforced concrete. As of now there is no general agreement relating to the methodolo- gy to be adopted in the case of design or testing methods of such fibers.
The Concrete Committee of the JSCE (Japan Society ofCivil Engineers)under the chairman ship of K. Kobayashi set up a subcommittee in 1989 for the research on continuous fiber reinforced material.
JSCE was entrusted by Association of composite material using continuous fiber for concrete rein- forcement (CCC President: Minoru SUGITA) to perform further research on CFRM. The subcom- mittee set up three working groups and also asked the members to perform individual research.
The results obtained from this subcommittee are as follows:
(1) Design Concept for Concrete members using Continuous Fiber Reinforced Materials (Chief: Yoshio KAKU'D\)
(2) Test Methods for Continuous Fiber Reinforced Materials (Chief: Atsuhiko MACHIDA)
(3) Concept for Durability of Continuous Fiber Reinforced Materials (Chief: Hiroshi SEKI)
(4) A State-of-the-Art Report on Continuous Fiber Reinforced Materials for Concrete Structures Among these, (1) to (3) are contained in this paper.
H. Okamura is a Professor in the Department of Civil Engineering at the University of Tokyo, Tokyo, Japan. His research interest include fatigue and shear of reinforced concrete members, durability design of reinforced concrete structures, application of FEM to reinforced concrete and development of high performance concrete.
