Non-linear finite-element investigation of the parameters affecting externally-bonded FRP flexural-strengthened RC beams

open access: yesResults in Engineering, 2020
This paper presents a three-dimensional non-linear finite-element model developed to simulate the behaviour of reinforced-concrete (RC) beams strengthened in flexure with carbon fibre-reinforced polymers (CFRP).

Effect of Bonding Layer on Guided Wave Mode Behavior in FRP Plate Bonded on Concrete

open access: yesJournal of the Korean Society for Nondestructive Testing, 2012
In this study, effects of bonding agent, e.g. epoxy, on the behavior of fundamental guided wave modes propagated in FRP plate bonded on a concrete, are investigated. Global matrix model of multilayered FRP-epoxy-concrete system was constructed to obtain the velocity and attenuation dispersion curves of the fundamental A0 and S0 modes.

Deflection behaviour of FRP reinforced concrete flexural members [PDF]

open access: yes, 2006
The design of fibre reinforced polymer (FRP) reinforced concrete (RC) can often be governed by the serviceability limit state of deflection. Currently, the evaluation of short-term deflection of FRP RC is undertaken using radically different approaches ...

Fracture analysis of debonding mechanism for FRP plates [PDF]

open access: yes, 2009
Inevitable flaws in the concrete-FRP interface govern plate debonding, and are not amenable to finite element analysis because the models require far more detail than will ever be available for the interface. This thesis describes a global-energy-balance

NUMERICAL INVESTIGATION OF THE PERFORMANCE OF INSULATED FRP-STRENGTHENED REINFORCED CONCRETE BEAMS IN FIRE [PDF]

open access: yesCivil Engineering Journal, 2018
Fiber reinforced polymers (FRP) have been widely used in retrofitting and strengthening of deteriorated or deficient reinforced concrete (RC) elements. A major concern about those systems is their performance under elevated temperature which limits the ...

Improvement of capacity in bending by the use of FRP layers on RC beams [PDF]

open access: yesJournal of Civil Engineering and Management, 2005
Carbonâ€filled plastic bands are more extensively used for strengthening the permanently exploited curved elements. As a result, the bending rigidity of the element is increased and the crack formation process is changed. Investigation of these problems is carried out basing on the model of laminated material, in which the mechanical properties of ...

Adhesive Layer Modeling in Concrete Beam Strengthened with FRP in an EFG Framework

open access: yesPeriodica Polytechnica Civil Engineering, 2022
The main challenging issue in concrete beam strengthening with FRP plates is the insurance of their joint performance. As been reported, the external load is mainly the primary reason for plate separation. The applied force corresponding to the moment of failure is called the debonding load. This load is of great importance.

Optimizing the Flexural Strength of Beams Reinforced with Fiber Reinforced Polymer Bars Using Back-Propagation Neural Networks

open access: yesARO-The Scientific Journal of Koya University, 2016
The reinforced concrete with fiber reinforced polymer (FRP) bars (carbon, aramid, basalt and glass) is used in places where a high ratio of strength to weight is required and corrosion is not acceptable. Behavior of structural members using (FRP) bars is

Predicting the Torsional Strength of Reinforced Concrete Beams Strengthened with FRP Sheets in terms of Artificial Neural Networks [PDF]

open access: yesJournal of Structural and Construction Engineering, 2018
Reinforced concrete (RC) structural elements such as peripheral beams, beams supporting the canopy, ring beams of circular slabs are common members which could encounter torsional moments.
