An Experimental Study on Tensile Characteristics for Strand Type FRP Tendon in Development

This paper presents the results of tensile characteristics for developing FRP tendon with strand type. The performance targets were decided to compare the tensile characteristics of developing FRP tendon. Test specimens were manufactured by applying some improvements to enhance the tensile characteristics. The influence factors on the tensile characteristics have been found from the test results. Those are the fiber weight fraction, the pitch, the FRP cross sectional area, and the type of external fibers. The tensile characteristics were satisfactory compared to the performance targets.
