Bond Performance of Near-Surface Mounted BFRP Bars to Concrete

The International Conference on Civil Infrastructure and Construction, 2023
This paper presents the test results of a study on the bond performance of near-surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars to concrete. Twelve C-shape concrete specimens were tested under direct pull-out loading configuration. Test parameters included the bar surface configuration (deformed and sand coated), the types of epoxy ...

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 ...

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.

Design of a model mount for near-surface submarine experiments

2022
A wire suspension mount will greatly minimize mount interference and allow enough flexibility for a model to react appropriately without distortion of the reaction forces. This paper explores the initial steps to design this mount by developing a mathematical model to validate wire suspension as a viable mounting method for water environments.

Concrete Structures Strengthened with near Surface Mounted Reinforcement of CFRP

Advances in Structural Engineering, 2003
The need of maintenance, repair and upgrading of concrete structures has increased considerably over the last decade and will most likely continue to do so. There can be several reasons for this, but it can often be attributed to normal change of use, increased demands on the structure, errors in the design and/or construction phase or in the worst ...

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

Vortex dynamics in the near wake of a surface-mounted hemisphere

Physics of Fluids
The dynamics of vortical structures for the flow over an isolated surface-mounted hemisphere are investigated with time-resolved particle image velocimetry and hydrogen bubble visualization techniques. The 10 mm height hemisphere is completely submerged in the laminar boundary layer, and the Reynolds number based on the hemisphere height is 780.

On the strengthening of RC beams with near surface mounted GFRP rods

Composite Structures, 2014
Abstract Inserting FRP rods into grooves using the NSM technique has been demonstrated to be a suitable method for repairing or strengthening RC beams. Recently, the availability of NSM GFRP rods has been highlighted notwithstanding low elasticity and shear modulus.

Scalar transport in the near aerodynamic wakes of surface-mounted cubes

Atmospheric Environment (1967), 1978
Abstract The paper describes investigations in the near wake regions of surface-mounted cubes of various sizes in boundary layers of contrasting thicknesses. Measurements were made of the near wake residence time of artificially-injected scalars (smoke) and of the cavity length.
