Texto completoIn the field of construction, concrete is the most common material used to construct buildings, bridges... With its great history, there are a large number of structures that is found degraded for many reasons such as road accidents, changes in traffic, load changes in buildings or climate action ...To resolve these issues, two main options available to project owners: the reconstruction or repair. Reconstruction is an interesting solution but is very expensive and cannot be applied to all structures (historical works ...). The second solution is often used to keep the structures under service conditions. A repair methods commonly used is the application of composite materials to strengthen reinforced concrete structures. The relatively acceptable cost and rapid implementation make this technical solution increasingly appreciated. The Flax fiber is a natural material which has good mechanical properties. At present, the flax fiber is applied in several areas: automotive, sports ... In the civil engineering field, with its good mechanical properties, flax fiber can be used in the field of building Reinforced Concrete structures substitution of regular fibers (carbon fiber, fiberglass ...) The aim of this thesis is the evaluation of the ability to use flax fibers in strengthening reinforced concrete beams. The study will focus on a case of shear reinforcement that is not well documented in the literature; it will be compared with the reinforcement with carbon fibers. The experimental program was carried out on 3-point bending tests with the support of load approach for a strong shear in the area concerned on rectangular beams and T-beams. The beams are reinforced by bidirectional flax fabrics and unidirectional reinforcement and different configurations. The calculation standards ACI, FIB, CSA, CNR-DT ... recommended to calculate structures with carbon reinforcements and glass in building for shear strengthening are applied to ensure their effectiveness in the case of a reinforcement flax fibers. Finally, a numerical model is being studied by the finite element method to reproduce the behavior of beams reinforced with natural fiber to study the parameters that play an important role in shear strengthening of concrete beams reinforced with flax fiber. The results show that the reinforcing flax fiber has significant effects in the shear reinforcement of reinforced concrete beams (increase in shear resistance of 10% to 33%). The reinforcement by flax fiber has a mechanical capacity equivalent to that of carbon fiber in the shear reinforcement of reinforced concrete beams and potential in strengthening reinforced concrete structure. The results of the numerical model by the finite element method reflect a behavior similar to those obtained during the experimental tests. The model also valid flax fiber capacity comparable to that of carbon fiber in the shear strengthening of reinforced concrete beams

Texto completoA large number of existing buildings are faced with a lack of strength which may seriously compromise the security of persons in the case of seismic shaking. These buildings, conceived initially for vertical loading, were rarely designed and constructed so as to take up lateral seismic shaking movements. In the aim of improving the strength of these existing buildings, and hence attenuate the risks that may be induced, their rehabilitation and strengthening are of a strategic interest. The glued reinforcing technique in composite materials is widely being used as a new strengthening technique in structures. This technique is particularly interesting for the repair and strengthening of reinforced concrete structures. In the aim of reducing the cost and ensuring a relatively more ductile behaviour for the strengthened reinforced concrete elements, the addition of glass fibres could be considered as a replacement solution since glass fibres are relatively more deformable and with a lesser cost compared to carbon fibres. In this sense, the present work aims at evaluating the efficiency of external strengthening in FRP fabric (glass, carbon) on reinforced concrete elements. The study evaluate the influence and the efficiency of external strengthening of reinforced concrete beams and reinforced concrete bam-column joints using glass-FRP and carbon-FRP tissues in different strengthening configurations. These configurations combine the separate use of carbon fibres and glass fibres tissues unidirectional with a U-shaped anchorage, together with a bidirectional hybrid fabric glass-carbon fibre. A total of ten reinforced concrete beams and eleven reinforced concrete beam-column joints, were strengthened and tested under cyclic loading for the beams and alternate loading for the joints. The testing data analysed concerned the strength, the stiffness, the ductility and the failure mode. They clearly show that the strengthening configuration in a U-shape has considerably improved the flexural strength and contributed to the redistribution of internal forces, enabling the deformations of beams to increase. The use of a hybrid strengthening pattern glass-carbon unidirectionally was more efficient. It represents an advantageous solution for the strengthening of reinforced concrete structures

Texto completoThe aim of the experimental program developed in this work is to investigate the possibility of using Carbon Fiber Reinforced Polymer (CFRP) rods to strengthen concrete structural members with the Near Surface Mounted reinforcement (NSM) technique. We study some physical and mechanical proprieties of CFRP rods and their interaction with the concrete. Bonding at the interface between the CFRP rod and the filling material and that between the filling material and the old concrete is studied. The global behavior both of reinforced concrete beams strengthened by NSM technique and subjected to flexure and of cantilever beams is investigated. We make an important parametric study of some variables. The experimental results are compared with the analytical and finite–element calculations of the principal limit states. The failure moments of beams in various failure modes are also compared. Finally, the stiffness of the strengthened beams during loading and unloading cycles is studied by analytical and Finite Element methods. The experimental results indicate that strengthening concrete structural members with the Near Surface Mounted reinforcement technique gives very satisfactory results

Texto completoThe study on strengthening or repairing reinforced concrete structures by bonding composite materials has been widely carried out for more than two decades. The mechanical and physical advantages on flexural strength, shear strength, mechanical behaviour, durability, reinforcement efficiency have been well approved. The methods of reinforcement by composite materials can be distinguished as internal reinforcement, external reinforcement and hybrid reinforcement. In this work, the hybrid reinforced concrete beams were studied. Reinforcement in bending is provided by steel and composite materials, CFRP plate. Two bonding methods between the concrete surface and the CFRP plate surface are proposed: direct bonding and bonding using an epoxy resin layer. In this study, three different series of hybrid-reinforced beams were used: a direct bond between the two materials, the second with an adhesive bond between the two materials and the last with a specific bond. The mechanical performance of these beams, mechanical behaviour, failure modes, ultimate load, load corresponding to the first cracks in the concrete, load corresponding to the plasticization of the longitudinal steel and the influence of the adhesion between the concrete surface and the surface of the CFRP plate were analysed. The numerical finite element method was also used to analyse the mechanical performance of the beams. The results provide new knowledge on the mechanical advantages of hybrid reinforced concrete beams
