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.

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.

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.

Book Synopsis Retrofitting of Concrete Structures by Externally Bonded FRPs, With Emphasis on Seismic Applications by : fib Fédération internationale du béton
Download or read book Retrofitting of Concrete Structures by Externally Bonded FRPs, With Emphasis on Seismic Applications written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2006-01-01 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 35 is the first bulletin to publish documentation from an fib short course. These courses are held worldwide and cover advanced knowledge of structural concrete in general, or specific topics. They are organized by fib and given by internationally recognized experts in fib, often supplemented with local experts active in fib. They are based on the knowledge and expertise from fib's ten Commissions and nearly fifty Task Groups. fib Bulletin 35 presents the course materials developed for the short course "Retrofitting of Concrete Structures through Externally Bonded FRP, with emphasis on Seismic Applications", given in Ankara and Istanbul in June 2005. The course drew on expertise both from outside Turkey and from the large pool of local experts on this subject. In most countries of the world, the building stock is ageing and needs continuous maintenance or repair. Moreover, the majority of existing constructions are deficient in the light of current knowledge and design codes. The problem of structural deficiency of existing constructions is especially acute in seismic regions, as, even there, seismic design of structures is relatively recent. The direct and indirect costs of demolition and reconstruction of structurally deficient constructions are often prohibitive; furthermore they entail a substantial waste of natural resources and energy. Therefore, structural retrofitting is becoming increasingly widespread throughout the world. Externally bonded Fibre Reinforced Polymers (FRPs) are rapidly becoming the technique of choice for structural retrofitting. They are cleaner and easier to apply than conventional retrofitting techniques, reduce disruption to the occupancy and operation of the facility, do not generate debris or waste, and reduce health and accident hazards at the construction site as well as noise and air pollution in the surroundings. fib Bulletin 35 gives state-of-the-art coverage of retrofitting through FRPs and presents relevant provisions from three recent standardisation milestones: EN 1998-3:2005 "Eurocode 8: Design of structures for earthquake resistance - Part 3: Assessment and retrofitting of buildings", the 2005 Draft of the Turkish seismic design code, and the Italian regulatory document CNR-DT 200/04, "Instructions for Design, Execution and Control of Strengthening Interventions by Means of Fibre-Reinforced Composites" (2004).

Download or read book FRP Reinforcement in RC Structures written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2007-01-01 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 40 deals mainly with the use of FRP bars as internal reinforcement for concrete structures. The background of the main physical and mechanical properties of FRP reinforcing bars is presented, with special emphasis on durability aspects. For each of the typical ultimate and serviceability limit states, the basic mechanical model is given, followed by different design models according to existing codes or design guidelines. Composite FRP materials are still relatively new in construction and most engineers are unfamiliar with their properties and characteristics. The second chapter of this bulletin therefore aims to provide practising engineers with the necessary background knowledge in this field, and also presents typical products currently available in the international market. The third chapter deals with the issue of durability and identifies the parameters that can lead to deterioration, which is necessary information when addressing design issues. A series of parameters is used to identify the allowable stress in the FRP after exposure for a specified period of time in a specific environment. The bulletin covers the issues of Ultimate Limit States (primarily dealing with flexural design), Serviceability Limit States (dealing with deflections and cracking), Shear and Punching Shear and Bond and Tension Stiffening. It provides not only the state-of-the-art but also in many cases ideas for the next generation of design guidelines. The final chapter deals with the fundamental issue of design philosophy. The use of these new materials as concrete reinforcement has forced researchers to re-think many of the fundamental principles used until now in RC design. The bulletin ends with a discussion of a possible new framework for developing partial safety factors to ensure specific safety levels that will be flexible enough to cope with new materials.

This book was released on 2015-08-25 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyses the current knowledge on structural behaviour of RC elements and structures strengthened with composite materials (experimental, analytical and numerical approaches for EBR and NSM), particularly in relation to the above topics, and the comparison of the predictions of the current available codes/recommendations/guidelines with selected experimental results. The book shows possible critical issues (discrepancies, lacunae, relevant parameters, test procedures, etc.) related to current code predictions or to evaluate their reliability, in order to develop more uniform methods and basic rules for design and control of FRP strengthened RC structures. General problems/critical issues are clarified on the basis of the actual experiences, detect discrepancies in existing codes, lacunae in knowledge and, concerning these identified subjects, provide proposals for improvements. The book will help to contribute to promote and consolidate a more qualified and conscious approach towards rehabilitation and strengthening existing RC structures with composites and their possible monitoring.

Book Synopsis Numerical Analysis of Debonding Mechanisms of Externally Bonded FRP Reinforcement in RC Beams by : Michael Cohen
Download or read book Numerical Analysis of Debonding Mechanisms of Externally Bonded FRP Reinforcement in RC Beams written by Michael Cohen and published by . This book was released on 2018 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is an urgent need to develop economic and efficient methods to repair and strengthen existing reinforced concrete structures. This demand is motivated by several factors including the aging of concrete structures, the desire to upgrade design standards, and the exposure to severe environmental effects. A particular problem confronting engineers in repairing deteriorated structures is the rehabilitation of reinforced concrete elements. Conventionally, steel plates were utilized to restore and enhance the tensile strength of damaged concrete members. Despite the effectiveness of this practice in terms of improving the structural capacity, it is still considered disadvantageous due to the excessive weight of steel and its susceptibility to corrosion in moist environments. The application of fibre reinforced polymer (FRP) to existing reinforced concrete structures has gained the interest of many researchers in the last few decades. These materials are superior to steel when it comes to comparing the resistance to electrochemical corrosion, strength-to-weight ratio, ease of handling, fatigue resistance, and availability in any length or shape. However, there is still a serious concern regarding the effect of premature debonding of the FRP plates before reaching the desired strength or ductility. This debonding can initiate from the ends of the plate or can be induced by intermediate cracks in the concrete member. Although the end-plate debonding and peeling mechanisms have been studied extensively, there is still a significant lack of data for FRP-strengthened beams in which intermediate crack-induced debonding is the dominant failure mode. On the other hand, the interfacial bond capacity between the concrete and the FRP composite has not been thoroughly investigated. Whereas, there is still need to study the effect of some of the mechanical and physical parameters on the bond strength of FRP-Concrete interface. Moreover, researchers have also shown a keen interest in simulating flexural cracks in concrete beams, and examine their effect on the debonding mechanisms of FRP materials. However, more realistic approach is needed to model cracks and account for their growth. In this study, a three-dimensional nonlinear finite element model was developed for simulating the flexural behaviour of RC beams externally bonded with FRP systems. The ABAQUS/CAE software version 6.14-2 was used for this purpose. This numerical analysis was performed based on a comprehensive experimental program conducted by Brena et al. (2003). The simulated RC beams were categorized in two groups: Control Beams (without fibre) and CFRP Beams (with carbon fibre reinforced polymer). During the process of constructing the CFRP beam models, two distinct procedures were followed to simulate the interface between the concrete and the externally attached FRP laminates. Perfect bond was assumed in the first approach, and a Cohesive Zone Model (CZM) was adopted in the second approach. In the latter, cohesive surface technique was implemented in the ABAQUS model through the use of traction-separation law. Despite the lack of quantitative evaluation in the literature as no similar techniques was attempted by others, the results of this numerical analysis were only compared with experimental findings, and the proposed models were found to be reliable. A parametric study was performed to investigate the influence of various parameters on the flexural capacity of the proposed beam model, and the debonding behaviour of the externally attached FRP laminate. This analysis was conducted by either changing the mechanical properties of some of the constitutive materials (e.g. concrete and reinforcing steel), or altering the geometrical and mechanical properties of the FRP reinforcement. It was then found that the effect of internal steel reinforcement ratio has the most impact on beam ultimate capacity. While changing the FRP bond length beyond a certain value bears no effect on beam strength. Moreover, the numerical model was modified to review the effect of intermediate crack spacings on the overall beam performance. A discrete crack approach was adopted to replicate crack propagation throughout the body of the beam. This technique has shown an approximately 30% improvement in the prediction capacity of this model when compared to a similar specimen in which smeared crack approach is used. The results of this analysis showed that the debonding behaviour of FRP laminates is largely influenced by crack spacing. In addition, the results have also indicated that the initiation of FRP micro-debonding was prolonged as crack spacings were decreased. This response can be attributed to the abrasion effect within the FRP-Concrete interface. Finally, this numerical analysis provides a relatively reliable guidance on the application and the mitigation of externally bonded FRP reinforcement in concrete beams. The predictive capability of the proposed FE models ensures their suitableness for further investigations of FRP effectiveness in civil engineering field.
