Bond characteristics of near surface mounted CFRP bars

Construction and Building Materials, 2013
Near Surface Mounted (NSM) strengthening is an emerging retrofit technique, which involves bonding fibre reinforced polymer (FRP) reinforcement into grooves cut into the surface of a concrete member to be strengthened. This technique offers many advantages over external bonding of FRP reinforcement, for example, an increased bond capacity and ...

Experimental and finite element analysis of flexural performance of RC beams retrofitted using near-surface mounted with CFRP composites and cement adhesive

Engineering structures, 2021
Fiber reinforced polymer (FRP) composite has been used effectively for the rehabilitation of concrete and steel structures in the last decades due to its excellent properties compared with conventional reinforcing materials such as steel.

Concrete Beams Strengthened with Prestressed Near Surface Mounted CFRP

Journal of Composites for Construction, 2006
Retrofitting concrete structures with fiber reinforced polymer (FRP) has today grown to be a widely used method throughout most parts of the world. The main reason for this is that it is possible to obtain a good strengthening effect with a relatively small work effort. It is also possible to carry out strengthening work without changing the appearance

Bond characteristics of near-surface-mounted anchorage for prestressing

Construction and Building Materials, 2017
Abstract The external bonds of carbon fiber reinforced polymers (CFRP) used to strengthen structures are known to be vulnerable to delamination. To prevent FRP delamination and efficiently strengthen structures, post-tension CFRP rods are installed for near-surface-mounted (NSM) strengthening.

Near Surface Mounted Shear Strengthening of Reinforced Concrete Beams

"SP-272: Antoine E. Naaman Symposium - Four Decades of Progress in Prestressed Concrete, FRC, and Thin Laminate Composite", 2010
This paper describes how four reinforced concrete T-beams were tested in order to study their behavior when strengthened for shear using near-surface mounted (NSM) bars. The objectives were to study the effects of the type of bars used (carbon fiber-reinforced polymer (CFRP) and conventional reinforcing steel) and the effects of the load level at which
