Abstract EN
Fiber reinforced polymer (FRP) has been proposed to replace steel as a reinforcing bar (rebar) due to its high tensile strength and noncorrosive material properties.
One obstacle in using FRP rebars is high price.
Generally FRP is more expensive than conventional steel rebar.
There are mainly two ways to reduce the cost.
For example, one is making the price of each composition cost of FRP rebar (e.g., fibers, resin, etc.) lower than steel rebar.
Another is making an optimized design for cross section and reducing the material cost.
The former approach is not easy because the steel price is very low in comparison with component materials of FRP.
For the latter approach, the cost could be cut down by reducing the material cost.
Therefore, an idea of making hollow section over the cross section of FRP rebar was proposed in this study by optimizing the cross section design with acceptable tensile performance in comparison with steel rebar.
In this study, glass reinforced polymer (GFRP) rebars with hollow section and 19 mm of outer diameter were manufactured and tested to evaluate the tensile performance in accordance with the hollowness ratio.
From the test results, it was observed that the tensile strength decreased almost linearly with increase of hollowness ratio and the elastic modulus decreased nonlinearly.
