Experimental Investigation on Tensile Mechanical Properties of CFRP-PCPs Composite Rebars

Article Preview

Abstract:

The behavior of CFRP-PCPs composite rebars on tensile test was studied. Experimental results showed that using CFRP-PCP composite rebars as reinforcement utilizes high strength of FRP effectively, reducing the reinforcement ratio and consequently the cost while simultaneously satisfying structural requirements. Tension stiffening in CFRP-PCPs composite rebars is significant when higher concrete strength and higher prestressing level are applied.
