The
Concrete Committee of the Japan Society of Civil Engineers set up a
"Research Committee on Continuous Fiber Reinforcing Materials
(CFRM)" in 1989, chaired by Prof. H.Okamura. The fee for the research
works was offered by the Association of Composite Materials using Continuous
Fiber for Concrete Reinforcement (CCC). The research committee's work
involved various aspects of CFRM, e.g. review of research works and actual
applications; study on how to design structures, to deal with durability
problems and on the test methods. The committee work was compiled as a
state-of-the art report on "Application of Continuous Fiber Reinforcing
Materials to Concrete Structures" and published in Japanese in the
journal, Concrete Library, No. 72 in 1992.
Another aim of the committee was to offer a chance to committee members to
study about the material by their own way in order to collect ideas on the
fundamental designing methods. The work done by the committee members was
published together with the research work done by other researchers in the
proceedings of the Symposium on Application of CFRM on Concrete Structures
(Concrete Engineering Series 1) in April 1992. A part of the work related to
the designing method and the state-of-the-art report was translated into
English and published as "State-of-the-Art Report on Continuous Fiber
Reinforcing Materials" (Concrete Engineering Series 3) in October 1993.
For CFRM to be widely used in the field of concrete, it is necessary to have
a set of guidelines for practical design and construction methods together
with the standard test methods and specifications. The Second Research
Committee on CFRM was thus set up by JSCE Concrete Committee, entrusted by CCC
and the Advanced Composite Cable Club (ACC), to prepare such guidelines. The
committee spent three years from November 1993 to October 1995 to come up
with its recommendations. The following four working groups were set up
within the committee:
(1) Design method
(Chairman: Prof. Y. Kakuta)
(2) Construction
methods (Chairman: Prof. T. Tsuji)
(3) Specifications
(Chairman: Prof. T. Uomoto)
(4) Standard test
methods (Chairman: Prof. H. Seki).
The
work done by the committee was published in Japanese in Concrete Library, No.
88, in 1996. The article includes recommendations for design and
construction, specifications, standard test methods and necessary data for
using CFRM.
This "Recommendation for Design and Construction of Concrete Structures
using Continuous Fiber Reinforcing Materials" (Concrete Engineering
Series 23) is a translated version of the above-mentioned report which was
written in Japanese. I hope that people throughout the world who use CFRM as
reinforcement for concrete structures will find the information contained in
this book useful.
