Abstract
This paper presents test results on the mechanical and self-sensing properties of CFRP bars and concrete beams reinforced with CFRP bars. The CFRP bars with different diameters were produced with different surface treatments. Eighteen CFRP bar specimens in three series were tested for elastic modulus, ultimate tensile strength and electrical resistance change. Six concrete beams reinforced with CFRP bars under third-point loading were tested. The curves of electrical resistance change of CFRP bars in concrete beams versus load were presented. The test results show that CFRP bars can be used as reinforcement and monitor the concrete structures mechanical properties.
