Abstract:
"The American Concrete Institute sponsored an unprecedented six technical sessions on FRP Reinforcement for Concrete at the Vancouver Conference on March 28-31, 1993. Speakers and attendees were present from Europe, Japan, Canada and the United States. The papers in this Special Publication are organized in the same subject areas as the conference. The subject topic areas and symposium sections are: 1. FRP Material Properties and Testing Methods 2. FRP Reinforcement for Reinforced Concrete 3. FRP Reinforcement for Prestressed Concrete 4. Analysis And Design 5. The Japanese National Project for FRP Development 6. Applications of FRP Reinforcement The 55 technical papers in this report represent the most comprehensive compilation to date of FRP research, design, and application information. A comparison of the papers provides an insight to the approach to the use and development of FRP reinforcement within the research communities of Europe, Japan and North America. The two symposium volumes are also significant because substantial portions of the extensive Japanese national research project have been translated into English. The Japanese papers provide an insight to both the magnitude of the technical work being conducted in Japan and the organization of the Japanese research program."

The permissible crack width of concrete members reinforced by reinforcing steels is generally determined by the durability of the member based on reinforcing steel corrosion. However, since FRP reinforcement does not corrode by rusting, another factor should control permissible crack width for FRP reinforced structures. Paper examines permissible crack width of FRP reinforced concrete members in terms of the esthetics of external appearance. As cracks are wider, appearance deteriorates. Since esthetic evaluation is subjective, the authors used a questionnaire survey to gather information from experts. The surveys were completed by members of the JSCE Research Subcommittee on Continuous Fiber Reinforcing Materials. After reviewing a statistical analysis of the results, the authors offer estimates for permissible crack width of FRP reinforced concrete members.

Presents the test results on fundamental mechanical properties of several kinds of continuous fiber bars. Three kinds of fiber materials (carbon, glass, and aramid) have been used. The shape of the deformed bars differed and the diameter was approximately constant (8 mm). Tensile strength, Young's modulus, tensile creep, and pullout bond strength were tested. The main results were that Young's modulus of carbon fiber bars is about two-thirds that of Young's modulus of steel bars, whereas that of glass fiber bars and aramid fiber bars are nearly one-third that of steel bars; also, the initial slip bond stress and maximum bond stress were more likely to differ with the shape of the continuous fiber bars than with the kinds of fiber materials.

To estimate the heat resistance of continuous fiber bar, tensile strength of several types of continuous fiber bars were examined under high temperature and ordinary temperature after heating and cooling. The temperature range was 60 to 400 C. It was found that the tensile strength of organic binder bar was recovered under ordinary temperature after heating and cooling compared with higher temperature. Organic binder bars showed little decrease of tensile strength at high temperature. Carbon and glass fibers have more heat resistance than aramid fiber bars.

An experimental investigation was carried out to study and evaluate the flexural performance of concrete beams reinforced with continuous fiber bars (main reinforcing bars and prestressing tendons). Two series of flexural tests were conducted, and the primary variables were fiber material, tensile reinforcement ratio, concrete compressive strength, and bond condition in prestressing tendon. Through this experimental study, the following facts were clarified. The flexural performance of concrete beams reinforced with continuous fiber bars can be evaluated by conventional methods used in concrete beams reinforced with steel bars. The ductility capacity of reinforced concrete beams can be controlled by the compressive failure of concrete, and in prestressed concrete beams, can be controlled by changing unbonded length of prestressing tendon.
