Abstract
There are many studies on application of fiber reinforced plastic rods (FRP rods) to the reinforcement of concrete members. Those fibers have high tensile strength, light weight and excellent corrosion resistance. But, they have also some defects such as low modulus of elasticity and low bond strength.
The authors have conducted the researches to utilize braided AFRP rods made from aramid fiber as PC tendons under static loading. It would be effective to improve the composite action between rod and concrete by means of braiding the fibers and using them as PC tendons. In addition, application of spirally formed shear reinforcement keeping the continuity of fibers have also investigated. On the otherhand, there are few past researches on the fatigue characteristics of members reinforced by FRP rods, subjected to shear force under cyclic loading.
In this paper, fatigue characteristics of concrete beams reinforced by braided AFRP rods are discussed from the experiments.
