21 Abstract 22 23 This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. For new 24 construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for 25 a host of reasons. The principles for design and construction have been established and proposed to industry by the American ...

This study develops an easy-to-conduct numerical calculation method to assess the effect of Textile Reinforced Mortar when used as externally bonded flexural strengthening technique in low-grade reinforced concrete beams from ancient structures (aged between 60 and 100 years old). Using materials main mechanical characteristics dimensions inputs, model defines behaviour strengthened elements. p...

Abstract The FRP material plays a major role as strengthening in RC structural elements. It is popularly used to improve the load carrying capacity and stiffness elements by wrapping with sheets (combination of GFRP & CFRP). usefulness laminates external at both sides full vertical strips interval 100mm on beams studied.. In this experimental study nine reinforced concrete were cast that th...

This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). The fundamental prin...

Externally bonded composites reinforcedwith high-strength fibers are increasingly popular in construction, especially in structures’ strengthening, where the best possible mechanical properties are required. At the same time the ability to autodetect threats is one of the most desirable features of contemporary structures. The authors of the paper have developed an intelligent fabric, wherein t...

The numerical modeling of structures is a widely preferable approach to investigate the structural behavior RC beams since it delivers inexpensive predictions for confirming required goals concurrently with reducing casting, testing time, and effort. Shear-strengthening reinforced concrete (RC) using externally bonded (EB) fiber-reinforced polymers (FRPs) has attracted much attention due fact t...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...
