Abstract

Nine beams strengthened with helical rib steel wire near-surface mounted(NSM) in the concrete cover under monotonous loads are tested, and cyclic loading, security, delay and bending deformation of reinforced concrete beams are systematically studied. Test results indicate that NSM helical rib steel wire can overcome the peeling of the strengthening material from externally bonded FRP laminates.Compared with non-strengthened beam. The strengthened beams can significantly improve its ultimate capacity, and the increase could be as much as 130.92%. The suitable failure modes was discussed for the NSM helical rib steel wire on the basis of the theory of concrete structure, and formulas were derived for the bend moment, the ultimate moment. The predicted results agree well with the measured values from the tests of the studies.
