Effect of load distribution on the behaviour of RC beams strengthened in flexure with near-surface mounted (NSM) FRP

Composite Structures, 2022
Abstract Debonding failures of FRP have been frequently observed in laboratory tests of reinforced concrete (RC) beams flexurally-strengthened with near-surface mounted (NSM) fibre-reinforced polymer (FRP). A number of numerical and theoretical studies have been carried out to predict debonding failures in NSM FRP-strengthened beams, and several ...

Effect of groove spacing on bond strength of near-surface mounted (NSM) bonded joints with multiple FRP strips

Construction and Building Materials, 2017
Abstract In the strengthening of existing deficient structures using the near-surface mounted (NSM) FRP method, a group of parallel NSM FRP strips are usually needed to meet the capacity enhancement requirement. When the groove spacing (i.e., the net distance between grooves) is relatively small, the bond behaviour of each NSM FRP strip is ...

Reinforced concrete beams strengthened in flexure with near-surface mounted (NSM) CFRP strips: Current status and research needs

Composites Part B: Engineering, 2017
Abstract The near-surface mounted (NSM) FRP strengthening technique has attracted worldwide attention as an effective alternative to the externally bonded (EB) FRP strengthening technique. In the NSM FRP strengthening method, grooves are first cut in the concrete cover of a concrete member for the FRP reinforcement to be inserted and embedded using ...

Developing an anchored near-surface mounted (NSM) FRP system for fuller use of FRP material with less epoxy filler

Composite Structures, 2019
Abstract Near-surface mounted (NSM) FRP systems have a number of advantages over externally bonded (EB) FRP systems. Relying exclusively on epoxy-filler bond, however, conventional NSM FRP systems cannot ensure the tensile strength of FRP reinforcements to be fully developed.

Strength model for end cover separation failure in RC beams strengthened with near-surface mounted (NSM) FRP strips [PDF]

Engineering Structures, 2016
Abstract As an alternative to externally bonded FRP reinforcement, near-surface mounted (NSM) FRP reinforcement can be used to effectively improve the flexural performance of RC beams. In such FRP-strengthened RC beams, end cover separation failure is one of the common failure modes.
