“…In addition, in beams type -a (notched beams) the development of strain at mid-span was monitored using strain gauges placed on the reinforcement and concrete surface. A more detailed account on the experimental setup was previously reported in [32,33]. …”

“…The effect of concrete strength, reinforcement ratio and level of sustained load on both deflection and cracking were examined. An in depth discussion on the short-term and the long-term deflection behaviour of the tested specimens is reported in [32,33], while the present study focuses on examining the initiation and evolution of cracking under different loading conditions. The results from the tests undertaken on ten of the tested specimens, comprising both GFRP and steel RC beams, are discussed in the following in terms of crack width and crack spacing and are used to assess the performance of existing models to estimate the cracking behaviour of FRP RC elements, including ACI 440.1R-06 [5], Eurocode 2 [24] and Model Code 2010 [25].…”

“…Similar results were obtained by Miàs et al (2013b) who investigated long-term deflections of FRP RC elements. However, it is important to note that a long-term deflection increment depended on the longitudinal reinforcement ratio growing with the increased cross-section of FRP reinforcement (Miàs et al 2013a).…”

Fiber reinforced polymers (FRPs) are considered to be a promising alternative to steel reinforcement, especially in concrete structures subjected to an aggressive environment or to the effects of electromagnetic fields. Although attempts to develop effective reinforcement have been followed, the application of FRPs remains limited by the solution to simple structural problems that mainly appear due to the absence of design codes, significant variation in the material properties of FRP composites and limited knowledge gained by engineers as regards the application aspects of FRP composites and structural mechanics of concrete elements reinforced with FRPs. To fill the latter gap, the current state-of-the-art report is dedicated to present recent achievements in FRPs applying practice to a broad engineers’ community. The report also revises the manufacturing process, material properties, the application area and design peculiarities of concrete elements reinforced with FRP composites. Along the focus on internal reinforcement, the paper overviews recent practices of applying FRP reinforced concrete (RC) elements in structural engineering. The review highlights the main problems restricting the application of FRPs in building industry and reveals the problematic issues (related to the material properties of the FRP) important for designing RC following the formulation of targets for further research.

“…FRP also has higher tensile strength compared to steel which makes it having higher durability. However, some types of FRP bars have low modulus of elasticity that leads to larger deformations of FRP reinforced concrete [7].…”

This study investigated the flexural performance of RC beams reinforced and strengthened with Glass Fiber Reinforced Polymer (GFRP) bars. Tropical climate effects such as heat and rain throughout the year may cause the concrete surface to gradually erode and it may expose the steel inside the beam. If the steel is exposed, it may be oxidized and thus decreasing the strength of the RC structure. To avoid this situation from happening, reinforcing and strengthening method may be applied as an alternative as it is believed to be able to increase the durability of the structure. Three beams were constructed in this study. The first beam is a control beam. Second is a beam that longitudinally reinforced with steel at compression and GFRP bars at tension. The third beam is a beam reinforced with steel and strengthened by NSM method with GFRP bar at the tension zone. All three beams have the same dimension of 125mm x 300mm x 1800mm (width; height; length). All three beams were subjected to flexural test under four point static loads until failure. The result shows that the beams reinforced and strengthened with GFRP bars were seen to have higher stiffness compared to the control beam by 8% and 16% respectively. This proves that reinforcing and strengthening the RC members using FRP material can significantly improve the flexural capacity.
