Technique for Shear Strengthening—An Experimental Approach
2018This chapter presents the experimental procedure for shear strengthening of RC T-beams strengthened in shear with GFRP sheet. The job is performed primarily in two stages. The first stage consists of selection and testing of relevant materials for the preparation of test specimens in the laboratory to establish the physical and mechanical properties of

Numerical Approach to Shear Strengthening of Beams
2018Finite element method (FEM) is used to study the behaviour of RC T-beams strengthened in shear with GFRP sheet under two-point loading condition. The finite element analysis is carried out in this study using ANSYS finite element software. Specimens without GFRP as control beams, designated as S0-0L, S300-0L and S200-0L and beams strengthened with GFRP

Shear strengthening of beams with composite materials
2004This paper presents the results of an experimental/analytical study aiming at obtaining a clear understanding of the underlying mechanisms of the shear strengthening of reinforced concrete beams with fibre reinforced polymers (FRP). Through the definition of the generalised constitutive law of a bonded FRP sheet, of the compatibility imposed by the ...

Theoretical Approach to Shear Strengthening of Beams
2018The shear strength of RC T-beams with and without GFRP obtained from experimental investigation is compared to the shear strength computed by the guidelines given in different standards such as American Concrete Institute (ACI 318-02), Canadian Standard Association (CSA A23.3-94) and Indian Standard (IS: 456-2000) building codes (without the provision ...

Shear strengthening of old concrete beams
Batiment International, Building Research and Practice, 1986In our March‐April issue last year, the author described work at the Czech Technical University in Prague on the use of epoxy resins to apply new flat reinforcement to old concrete beams in order to enhance or prolong their service life. Here, some further test results and general conclusions are presented on the application of this technique to shear ...

Shear Strengthening Effects with Varying Types of FRP Materials and Strengthening Methods
SP-230: 7th International Symposium on Fiber-Reinforced (FRP) Polymer Reinforcement for Concrete Structures, 2005Synopsis: The FRP system is a good alternative of the traditional shear strengthening technique. This study evaluates the shear strengthening effects on the reinforced concrete beams strengthened with varying types of FRP materials, CFRP, CFS and GFRP. The entire strengthened specimens were failed in the mode of brittle shear failure with debonding of ...

Strengthening of shear wall with high performance RC jacket
2008A new technique for the strengthening of existing R/C shear walls based on the application of thin high performance jackets is presented in this paper. The strengthening jacket is made of high performance concrete, having a compression resistance higher than 150 MPa, and reinforced by means of an high strength steel mesh.

Shear strengthening of reinforced concrete beams with various composite strengthening systems
2020Across Canada and around the world, damaged and aging infrastructure is a major issue facing civil engineers and infrastructure planners. Funding to replace these aging structures is unlikely to become available, therefore, economical repair techniques, which can return a structure to its original state are required.

SHEAR CAPACITY OF RC BEAMS STRENGTHENED WITH FRP LAMINATES
2002Shear strengthening of RC beams using fibre-reinforced polymer (FRP) composites has recently proved successful. Several experimental data mostly related to shallow beams have been collected, and design Equations have been proposed for the computation of the shear capacity of a strengthened RC beam taking into account the FRP contribution. As part of an
