Bond Performance of Near-Surface-Mounted FRP Bars

Journal of Composites for Construction, 2011
Near-surface-mounted (NSM) reinforcement has become a well-known method for strengthening existing concrete structures. The bond between the NSM reinforcing bars and concrete is the key factor in the NSM technique. In the NSM technique, there are two bond interfaces: one between the NSM bar and the adhesive, and the other between the adhesive and the ...

Near-surface mounted FRP reinforcement: An emerging technique for strengthening structures

Composites Part B: Engineering, 2007
Abstract Near-surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement is one of the latest and most promising strengthening techniques for reinforced concrete (RC) structures. Research on this topic started only a few years ago but has by now attracted worldwide attention.

Interfacial stress transfer of near surface-mounted FRP-to-concrete joints

Engineering Structures, 2008
Adhesively bonding carbon FRP (CFRP) plates to the surfaces of reinforced concrete structures is now a well-established form of retrofitting with advanced design rules and mathematical models that quantify the debonding mechanisms. However, externally bonded plates tend to debond at low strains which limits the effectiveness of this retrofitting ...

Characterization of FRP Rods as Near-Surface Mounted Reinforcement

Journal of Composites for Construction, 2001
The use of near surface mounted (NSM) fiber-reinforced polymer (FRP) rods is a promising technology for increasing flexural and shear strength of deficient reinforced concrete (RC) members. As this technology emerges, the structural behavior of RC elements strengthened with NSM FRP rods needs to be fully characterized. Given the variability of material

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 ...

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

Strengthening of RC members with near-surface mounted CFRP rods

Composite Structures, 2009
The aim of the experimental programme developed in this work was to investigate the possibility of using Carbon Fibre-Reinforced Polymer (CFRP) rods to strengthen concrete structural members with the near-surface mounted reinforcement (NSM) technique.

Bond characteristics and modeling of near-surface mounted CFRP in concrete

Composite Structures, 2021
Abstract This paper presents the direct pull-out test results of twenty-four concrete joint specimens using near-surface mounted (NSM) carbon fiber-reinforced polymer (CFRP) rods and strips. Investigated in the study was the effect on the bond strength and local bond characteristics due to different cross-sectional shape (rod vs.
