This book was released on 2001-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In December 1996, the then 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 1998, this Task Group became fib TG 9.3 FRP Reinforcement for concrete structures in Commission 9 Reinforcing and Prestressing Materials and Systems. The Task Group consists of about 60 members, representing most European universities, research institutes and industrial companies working in the field of advanced composite reinforcement for concrete structures, as well as corresponding members from Canada, Japan and USA. Meetings are held twice a year and on the research level its work is supported by the EU TMR (European Union Training and Mobility of Researchers) Network "ConFibreCrete”. The work of fib TG 9.3 is performed by five working parties (WP): Material Testing and Characterization (MT&C) Reinforced Concrete (RC) Prestressed Concrete (PC) Externally Bonded Reinforcement (EBR) Marketing and Applications (M&A) This technical report constitutes the work conducted as of to date by the EBR party. This bulletin gives detailed design guidelines on the use of FRP EBR, the practical execution and the quality control, based on the current expertise and state-of-the-art knowledge of the task group members. It is regarded as a progress report since it is not the aim of this report to cover all aspects of RC strengthening with composites. Instead, it focuses on those aspects that form the majority of the design problems. several of the topics presented are subject of ongoing research and development, and the details of some modelling approaches may be subject to future revisions. as knowledge in this field is advancing rapidly, the work of the EBR WP will continue. Inspite of this limit in scope, considerable effort has been made to present a bulletin that is today’s state-of-art in the area of strengthening of concrete structures by means of externally bonded FRP reinforcement.
Book Synopsis Strengthening RC T-beams in Flexure and Shear Using New Mechanically-anchored FRP and Dry Fibre Systems by : Amir Mofidi
Download or read book Strengthening RC T-beams in Flexure and Shear Using New Mechanically-anchored FRP and Dry Fibre Systems written by Amir Mofidi and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current conventional strengthening of reinforced concrete (RC) beams using epoxy-bonded fibre-reinforced polymer (FRP) technique requires difficult surface preparation and is susceptible to a brittle form of failure due to peel-off or debonding of the FRP laminate from the beam. This research presents two new mechanically-anchored FRP and dry fibre strengthening systems that can be used to improve the performance of RC beams in flexure and shear, respectively. Unlike conventional FRP-strengthening methods, the proposed systems require less surface preparation and adhesive application, and eliminate peel-off and debonding of FRP sheets. In order to experimentally evaluate the effectiveness of the new strengthening systems, a total of seven half-scale RC T-beams were tested under four-point loading system up to failure. Three RC T-beams were tested to evaluate the increase in shear capacity using a new FRP strengthening system. One beam was tested as a control beam. One beam was strengthened by using a U-shaped carbon FRP (CFRP) sheet that was externally bonded to the web of the beam. One beam was strengthened by using new anchored U-shaped dry carbon fibre (CF) sheet method. In this method, dry CF sheets are wrapped around and bonded to two steel rods. Then the rods are anchored to the corners of the web-flange intersection of the T-beam with mechanical bolts. The new method relies on utilizing the full mechanical contribution of the dry CF sheets, which will be activated upon development of strain in the RC web, and transferring them through a longitudinal steel rod to the core of the compression web-flange zone by means of mechanical anchors. Four RC T-beams were tested to evaluate the increase in flexural capacity and ductility using a new FRP strengthening system. One beam was tested as a control beam. One beam was strengthened with conventional epoxy-bonding method. Two beams were strengthened with the new hybrid FRP sheet / ductile anchor system (one with unbonded CFRP, while the other with bonded CFRP). The proposed system leads to a ductile failure mode by triggering the yield in the steel anchor system (steel links) while avoiding peel- off or debonding of FRP sheets, which is sudden in nature. The tested beams where modeled to analytically evaluate their performance. The experimental and analytical results indicate that the proposed new retrofitting methods are structurally efficient in enhancing the shear and flexure strengths and ductility of RC T-beams compared to conventional epoxy-bonding methods.

Download or read book Strengthening of Reinforced Concrete Structures written by L C Hollaway and published by Elsevier. This book was released on 1999-03-05 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The in situ rehabilitation or upgrading of reinforced concrete members using bonded steel plates is an effective, convenient and economic method of improving structural performance. However, disadvantages inherent in the use of steel have stimulated research into the possibility of using fibre reinforced polymer (FRP) materials in its place, providing a non-corrosive, more versatile strengthening system. This book presents a detailed study of the flexural strengthening of reinforced and prestressed concrete members using fibre reinforces polymer composite plates. It is based to a large extent on material developed or provided by the consortium which studied the technology of plate bonding to upgrade structural units using carbon fibre / polymer composite materials. The research and trial tests were undertaken as part of the ROBUST project, one of several ventures in the UK Government's DTI-LINK Structural Composites Programme. The book has been designed for practising structural and civil engineers seeking to understand the principles and design technology of plate bonding, and for final year undergraduate and postgraduate engineers studying the principles of highway and bridge engineering and structural engineering.

This book was released on 2019-05-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Effect of Flexural NSM-FRP Bars on the Shear Strength of Reinforced Concrete Beams by : Rayyan Bashar Saleh
Download or read book Effect of Flexural NSM-FRP Bars on the Shear Strength of Reinforced Concrete Beams written by Rayyan Bashar Saleh and published by . This book was released on 2019 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Strengthening of reinforced concrete (RC) members in flexure and shear, using fiber-reinforced polymer (FRP) laminates and near surface mounted (NSM) bars has been developed over the last few decades. Conventionally, FRP composite laminates are attached to the vertical sides of RC beams to increase their shear strength. However, in some cases, the sides of the beam might be inaccessible or shallow. According to the ACI 318-14 guidelines and other codes of practice, longitudinal reinforcement contributes to the shear strength of RC beams. The objective of this study is to assess experimentally the effect of longitudinal NSM bars, which are mounted to the beam’s sides, on the shear strength of RC beams. The variables of the experimental program included the beam’s depth to evaluate the size effect, the concrete compressive strength, and the flexural FRP reinforcement ratio. A total of 18 shear deficient RC beams were built, strengthened with longitudinal NSM bars, and tested under three-point bending until failure. It was observed that the strengthened beam specimens exhibited an increase in shear capacity that ranged from 10 to 35% over the control beams. It was also observed that the increase in the concrete shear strength with longitudinal FRP bars for the high strength concrete specimens was not as effective as that with normal concrete strength specimens. The results have also revealed that the size effect phenomena has a significant effect on the test results, in which the increase in shear strength has decreased from around 35% to 10%, with the increase of beam's height from 230 to 650 mm, respectively. It was concluded that equation 22.5.5.1 of the ACI 318-14 code, which gives a simplified expression for the concrete contribution to the shear strength of beams, is not conservative for beams with large depths. Thus, other published analytical shear strength models that account for size effect were utilized in this study to predict the strength of the tested specimens. This study utilized 10 different analytical models in predicting the shear strength of the tested RC beam specimens. The models that showed the closest agreement with the tested data were the University of Houston method and the model based on the second order simplified modified compression field theory. It can be concluded that flexural longitudinal NSM bars could be used as a viable solution to enhance the shear strength of RC beams."--Abstract.
