New Method for Testing Fiber-reinforced Polymer Rods Under Flexure
This paper provides a new test method to determine the flexural properties of FRP reinforcing rods for material specifications, research and development, quality assurance, and structural design and analysis. This test method specifies the requirements of four-point flexural tests on FRP rods used in place of steel reinforcement or prestressing tendon in concrete on the basis of the knowledge gained from research results. This test method follows the ASTM standard test methods with some modifications according to the intended purpose and easy realization of the tests. Furthermore, flexural verification tests have been conducted on six sizes of diameters of GFRP rods, from #3 to #8 and each having six specimens. The test results were discussed and compared with that obtained from the three-point flexural tests as specified by the ASTM standard test method for flexural properties of fiber reinforced pultruded plastic rods.
