Book Description
Strengthening Design of Reinforced Concrete with FRP establishes the art and science of strengthening design of reinforced concrete with fiber-reinforced polymer (FRP) beyond the abstract nature of the design guidelines from Canada (ISIS Canada 2001), Europe (FIB Task Group 9.3 2001), and the United States (ACI 440.2R-08). Evolved from thorough cla

Book Description
Sets out basic theory for the behavior of reinforced concrete structural elements and structures in considerable depth. Emphasizes behavior at the ultimate load, and, in particular, aspects of the seismic design of reinforced concrete structures. Based on American practice, but also examines European practice.

Book Description
In December 1996, CEB established a Task Group with the main objective to elaborate design guidelines for the use of FRP reinforcement in accordance with the design format of the CEB-FIP Model Code and Eurocode2. With the merger of CEB and FIP into fib in June 1998, this Task Group became fib TG 9.3 FRP Reinforcement for concrete structures in Commission 9 Reinforcing and Prestressing Materials and Systems. Finally, as a result of the restructuring of fib’s Commissions and Task Groups at the end of 2014, the Task Group became fib T5.1 FRP Reinforcement for concrete structures, chaired by Stijn Matthys at Ghent University, in Commission 5 Reinforcements. The work of former TG 9.3 and current T5.1 was performed by two working parties (WP), one of which is “Externally Applied Reinforcement” (EAR), which produced fib bulletin 14 “Externally bonded FRP reinforcement for RC structures” in July 2001. Following a number of years of relatively slow activity, the WP on externally applied reinforcement was reactivated and started working on an update of bulletin 14. The result of this work is summarised in the present technical report, which aims to give design guidelines on the use of externally applied FRP reinforcement (both externally bonded and near-surface mounted) for concrete structures. An attempt has been made to present some of the topics in a Eurocode-compatible format, so that the material covered may form the basis for the introduction of composites in the next version of Eurocode 2 and for the updating of the text on seismic retrofitting with composites in the next version of Eurocode 8. All persons who participated in the preparation of this Bulletin are mentioned in the copyright page. Further acknowledgements are due to Josée Bastien (Canada), Hans Rudolf Ganz (Switzerland) and Luc Taerwe (Belgium) for revision of the document. To all members of the working party on externally applied reinforcement our sincere thanks are expressed for the high quality and extensive work brought in on a voluntary basis.

Book Description
ABSTRACT: The enclosed work focuses on shear strengthening of reinforced concrete beams with carbon fiber sheets. The use of composite materials is increasing in rehabilitation of concrete structural elements. The advantages over concrete are high strength to weight ratio and high resistance to corrosion over steel structures. Over time, concrete beams lose their strength due to corrosion of the reinforcement inside the beam. To replicate this condition in the field, research on concrete beams was performed and experimental tests and analytical investigations were conducted to prove the validity of the research. Several T-shape rectangular beams were tested, and they were externally reinforced with carbon fiber. The bonding of the material to the concrete surface, the surface preparation, and the orientation of the fiber were important factors in strengthening the beam in shear. Two samples were tested in as-build conditions. Four other samples were externally reinforced with carbon fabric composite sheets. By applying the carbon externally, significant improvement on the shear strength of the concrete beam was achieved. Samples were modeled in a finite element (FE) program, ABAQUS, to verify the actual conditions acting on the beam during testing. The FE results were found to be similar to the experimental findings.

Book Description
Studies have shown that fiber-reinforced polymer (FRP) wraps can improve the capacity of rectangular beam sections. This technology has potential application to highway bridges that may have less shear capacity than flexural capacity or require added load capacity to handle current traffic demands. Compared with steel repair materials FRP offers several benefits, such as corrosion resistance and field-workability. Several studies have investigated the use of externally bonded FRP sheets to improve strength and stiffness of reinforced concrete (R/C) beams, but most have addressed flexural strength, not shear. The objective of the current study was to test the effectiveness of FRP wraps in repairing full-scale prestressed high-strength concrete joists fabricated with insufficient shear reinforcement. Four prestressed high-strength concrete tee-beams (joists) with integral web openings were tested. Two of the joists were repaired or upgraded with FRP wraps to improve shear performance and two were used as control specimens. Performance criteria were specified, and standard structural engineering practice for shear design was employed to determine wrap thickness. The results of the tests indicate that significant increases in the shear strength of R/C beams with insufficient shear capacity can be achieved by proper application of FRP wraps.

Book Description
Over the past two decades Fiber-Reinforced Polymer (FRP) composites has gained acceptance in civil engineering industry as a result of the urgent need to retrofit exiting constructed facilities and structures. This book focuses on the shear strengthening of reinforced concrete (RC) beams using FRP composites. Several research problems related to shear strengthening still linger and therefore require further research studies to be entirely solved. The main objective of this book is to experimentally and analytically study the FRP strengthening methods of full-scale RC beams in shear.
