要旨 1. INTRODUCTION
Many extensive researches have been carried out for the practical usage of Fiber Reinforced Plastics (FRP) rods in the fields of concrete structure construction. Since FRP rods are produce commercially a few years ago, there are still many unknown factors that must be made clear so that these materials can be used with safety and reliability.
The authors have conducted an experimental study on bond property of various FRP rods. Although no standard testing method for the FRP rods have been established, we referred to that of the provisional testing procedures of The Japan Society of Civil Engineers (JSCE).
Twelve kinds of FRP rods having different types of materials, matrix and diameters were used in this study. Some relationship between slippage and bond stress of different diameters and materials were investigated.
4. CONCLUSIONS
1. The bond strength of FRP rods in cement-concrete depend not only on the surface condition but also on fiber types, fiber strength, spiral-rod adhesion and spiral strength in spiral type FRP rods.
2. The bond-slip characteristics of all the FRP rods used in this experiment can be categorized in three groups. They are, a group with gradual-increasing bond-slip relationship, a group of sudden change of slip at a level and a group of sudden-change followed by gradual increment of bond with respect to slippage.
