Flexural strengthening of reinforced concrete beams with high-strength steel wire and engineered cementitious composites

Construction and Building Materials, 2020
The rehabilitation of reinforced concrete (RC) members with high-strength steel wire and polymer mortar is a popular method for structural strengthening, owing to the resultant high strength and good fire resistance.

Composite Timber Beams Strengthened by Steel and CFRP

Journal of Composites for Construction, 2017
AbstractComposite timber beams strengthened by U-shape steel sections and carbon fiber–reinforced plastic (CFRP) are studied experimentally in this paper. Specimens with various strengthening, i.e., steel only, CFRP only, and a combination of the two, were considered under three-point flexural tests. Failure, displacement and strain response, ductility,

Static strength tests of steel plate strengthened concrete beams

Materials and Structures, 1990
The behavior of damaged concrete beams strengthened by externally bonded steel plates is investigated experimentally. The variables tested were the thickness of the external steel plate, length and location of the interfacial crack, and the degree of surface preparation of the steel plate.

Experimental and analytical study on strengthening of reinforced concrete T-beams in shear using steel reinforced grout (SRG)

Composites Part B: Engineering, 2019
The use of steel reinforced grout (SRG) has emerged as a promising technique for the strengthening and retrofitting of reinforced concrete (RC) structures, however, the experimental evidence on its application for shear-critical RC beams is rather ...

Shear strengthening of simply-supported deep beams with openings incorporating combined steel-reinforced engineered cementitious composites and externally bonded carbon fibre-reinforced polymer sheets

Magazine of Concrete Research
In many practical applications, openings in deep beams are essential for accommodating services like ducts, pipes, and cables. However, these openings can significantly disrupt the load transfer mechanism and reduce the shear strength of the beam ...

Evaluation of Strengthening Steel Beams Using the Technique of Carbon Fiber Confinement by a Steel Plate (CFCSP)

, 2020
This research concentrates on evaluating the effect of using two new techniques for strengthening steel beams with carbon fiber–reinforced polymer (CFRP) strips on the structural behavior of these beams at service and ultimate load stages by using a ...

Design of CFRP-strengthened steel CHS tubular beams

Journal of Constructional Steel Research, 2012
Abstract External bonding of carbon fibre reinforced polymer (CFRP) sheets to the periphery of steel circular hollow sections (CHS) is a relatively new technique for structurally improving such sections. Design of CFRP sheets for strengthening tubular steel sections necessitates the prediction of the capacity of confined steel circular sections. This

Strengthening of glass beams with steel reinforced polymer (SRP)

Composites Part B: Engineering, 2014
Abstract The work describes an experimental analysis for studying the flexural strengthening of beams made from glass and composite material consisting of steel cords impregnated with polymeric resins (SRP). Beams were prepared consisting of glass sheets set vertically and reinforced on the intrados with SRP and subjected to four-point bending tests.

Mechanical Properties of Steel Crane Beam Strengthened by CFRP

Earth and Space 2010, 2010
In this paper, the mechanical properties of steel crane beam strengthened by carbon fiber reinforced polymer (CFRP) were researched in details. The research work was developed by the experimental method to principally examine the capacity of steel crane beams strengthened by CFRP under static loads and the anti-fatigue character under cyclic loads. The

Strengthening of RC T-beams with perforated steel plates

Magazine of Concrete Research, 2013
The study investigates the flexural behaviour and ductilities of reinforced concrete (RC) T-beams strengthened with perforated steel plates. A total of eight full-scale RC T-beams were tested. Three strengthened beams and a reference unplated beam were reinforced with closely spaced stirrups, while the remaining plated beams and reference beam did not ...
