Available in PDF, EPUB and Kindle. Book excerpt: Fiber reinforced polymer has recently become a popular replacement for steel rebar, used to reinforce concrete. Therefore much research is taking place to help develop and propose methods for best approximating the response of FRP reinforced members, to make them comparable to steel reinforced members. With this popularity comes multiple approaches to FRP deflection calculations. However, this study is significant, because it investigates the cracking moment equation adopted by ACI 318, in conjunction with state of the art deflection calculation methods. Specifically this research compares four deflection calculation methods. The first approach is proposed by Bischoff and implemented by ACI 440 in its latest revision. The second deflection calculation method is proposed by Rasheed et al. The third calculation is also suggested by Bischoff, as it is specific to four point bending. The fourth calculation method is proposed by this specific research and seeks to find a median between both the Bischoff and Rasheed equations. This fourth technique will be referred to as the Rasheed-Jacobs method, proposed to create a more conservative and relevant method for investigating the effect of cracking moment on the deflection calculations. This research was done with the help of Dr. Shawn Gross, and the database he had previously built through his investigation on FRP reinforced beams. Gross's database shows results for 106 samples tested using the actual experimental cracking moment as well as the ultimate moment capacity values. Of these 106 samples, 56 independent samples were used to investigate three different moment levels of 0.333Mn, 0.400Mn, and 0.467Mn. From this research, Gross's database was used to calculate the cracking moment of FRP reinforced beams based on ACI 318-08. A program was developed that uses the Gross database samples to calculate the cracking moment and deflection with the Rasheed, Bischoff, and Bischoff2 models as well as the new Rasheed-Jacobs model. This program calculates the Rasheed-Jacobs results, and then graphs the findings against the deflection values from the Rasheed, Bischoff, Bischoff2 models. These graphs showed very similar patterns amongst all four models, with the Rasheed-Jacobs results mainly falling on the more conservative side. However, when looking at the predicted deflection verse the Gross experimental deflection, the best results came from the 0.467Mn moment level, which shows consistent correlation while the lower moment levels are being less predictable using the cracking moment based on the ACI equation. It can reasonably be said that the 0.467M[subscript]n shows the best correlation between the four methods and the experimental results, because it is farther away from the actual nominal cracking moment of the FRP reinforced concrete beams.

This book was released on 2010-04 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased applications of FRP bars in buildings are possible only through better understanding of elevated temperature behaviours of FRP bar reinforced concrete (RC) structures as buildings are very vulnerable to fire hazard. Thirteen Carbon FRP bar RC beams have been used in the research described in this book. These beams were tested both at room and elevated temperatures. This book focuses on explaining both the experimental and theoretical behaviours of the tested beams. The theoretical responses of the beams were studied with the help of a strain compatibility analysis (SCA) and finite element modelling (FEM). SCA was carried out with the help of a layer-by-layer method of calculating section forces. A smeared crack approach was used for the FE analysis. The study suggested an appropriate modification in the ACI code deflection model for FRP RC structures. A method for the prediction of theoretical deflection of FRP reinforced beams is proposed for the European code. The research provided analytical models for the elevated temperature tests of FRP RC beams. The study also provided preliminary guidance for the design of FRP RC beams, in fire conditions.

This book was released on 2011-04 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the mechanical properties of Fibre Reinforced Polymers (FRP), serviceability limit states (SLS) often govern the design of FRP reinforced concrete (RC) structures. This study investigates the short-term serviceability behaviour of FRP RC beams through theoretical and experimental analysis. The experimental results on deformations, cracking and deflections are discussed. Prediction models provide adequate values of the experimental response up to the service load; however, an increment of the experimental deflection is obtained with respect to that provided by cracked section analysis when the load increases beyond the service condition. A discussion on the main aspects of the SLS of FRP RC is introduced, including the influence of the different parameters affecting the stresses in materials, maximum crack width and the allowable deflection. A methodology for the design of FRP RC at the serviceability requirements is presented. This procedure allows optimizing the overall depth of the element with respect to more generalised methodologies, since it takes account of the specific properties of materials and the loading conditions.

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.

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. - Detailed study of the flexural strengthening of reinforced and prestressed concrete members using fibre reinforced polymer composites - Contains in-depth case histories
