Abstract This paper presents the results of two wall-slab connection tests to study the effect of composite reinforcement materials. The tests are carried out at Scale 1 on X-shaped connections with a wall and a continuous floor on either side of the node. The geometry and steel rebars of the tested specimens are chosen in accordance with European constructive practice [1] . The composite reinforcement is a combination of CFRP, GFRP, and carbon mesh. To study the mechanical behavior of the node,...

Infilled frame structures have been a common form of construction. However, their behavior is one of the least understood and investigated among all the major construction systems. For a long time, these structures were built with a general lack of conclusive research and design information. An experimental program was undertaken which aims at investigating the behavior of masonry infilled RC frames strengthened with Ultra-High Performance Concrete (UHPC). In this study, UHPC cross diagonal stri...

Concrete buildings represent a large part of the world’s structures. Long-term effects represent a critical issue for this kind of construction making it necessary to develop reinforcement systems (i.e. composite materials). A large part of nowadays research is focused on composite materials study in terms of durability, resistance increase, and good practices. The present work investigates the influence of CFRP sheets reinforce in terms of global behavior and crack opening. Using digital image ...

Abstract In this study, the mechanical behaviour of a truss core glass-fibre reinforced polymer sandwich panel was analysed with an emphasis on the influence of the truss core geometry on the overall behaviour of the sandwich panel. First, the mechanical parameters of the sandwich components (skins and connectors) were experimentally determined, and compression, shear, and three-point bending tests were conducted to assess the main mechanical parameters of the specimens. Then, the analysed behav...

Abstract Composite structures have emerged over the past several years, and are being increasingly studied and applied in civil engineering projects. In this study, a composite structure was combined with timber under tension and concrete to resist compression. Although several connection systems to bind wood and concrete exist, an innovative system was applied in the present study based on a specific wood treatment and the use of adhesives. Eight hybrid timber-concrete composite (TCC) members w...

Abstract The combination of concrete and wood is well known in the rehabilitation of wood structures. In this paper, this association is used for reinforced concrete (RC) strengthening. Experiments were conducted to analyze the bending behavior of several combinations of wood-concrete composite beams with and without fiber-reinforced-polymer (FRP) bars. The results exhibit a significant effect of the reinforcement, essentially provided by the wood material. The presence of FRP bars seems to incr...

Abstract The main problem with carbon fibre reinforced polymers (CFRPs) in reinforcement is the bonding of the reinforcement to the concrete because the failure generally occurs by debonding. In the case of seismic loading, a high level of stress with cyclic loading may appear in the adhesive zone that's why this study focuses on the low-cycle fatigue of a concrete/CFRP interface under a high level of shear stress. It focuses on the influence of the fatigue loading amplitude on the service life ...

L’association du beton et du bois est bien connue dans la rehabilitation des structures bois. Dans cet article, cette combinaison est utilisee dans le renforcement des structures en beton arme. Des essais experimentaux ont ete menes pour analyser le comportement mecanique en flexion de plusieurs configurations en composite bois-beton avec ou sans barres en Polymeres Renforces par des Fibres. Les resultats montrent un effet significatif du renforcement, essentiellement du au materiau bois. La pre...

Since several years, composite structures emerged and are more and more studied and used in civil engineering. Wood-concrete structures have the advantage to improve the mechanical behavior on two points, the load capacity and the stiffness. The principle is to combine concrete which resists under compression and timber under tension. Several systems of connection exist to bond wood and concrete but an innovative system is used in this study based on a specific treatment of the wood and adhesive...
