This book was released on 2001 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigated the effectiveness of a new configuration of GFRP reinforcing bar as possible reinforcement for tension in reinforced concrete flexural members. Eleven concrete beams reinforced with two types of "web" bars were tested in flexure to failure. Five concrete beams reinforced with materials already being used in the construction industry were tested in flexure to failure. The results from these beam tests were compared with the results from the beams reinforced with the new web bars. Observations were made regarding mode of failure, cracking behavior, and deflection behavior of concrete beams using this new type of GFRP web bar reinforcement. A flexural analysis was performed to compare moment capacities using theoretical methods and ultimate moments from experimental results. A deflection analysis was performed to compare theoretical equations for effective moment of inertia, developed for simply supported FRP reinforced concrete beams, with the ACI model for conventional steel reinforced beams and deflection data from experimental results. Also, shear capacities and development lengths based on ACI 440 provisions were compared to the experimental results.

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 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of steel reinforcement in concrete structures results in significant repair and rehabilitation costs. In the past several years, new fiber reinforced polymer (FRP) reinforcing bars have been introduced as an alternative to steel reinforcing bars. Several national and international organizations have recently developed standards based on preliminary test results. However, limited validation testing has been performed on the recommendations of these standards. High variability of the tensile properties, degradation of tensile strength, direct shear capacity, predicted deflections due to creep, cracking behavior of FRP-reinforced concrete flexural members, bond behavior and development length, and effects of thermal expansion on cracking of FRP reinforced concrete have all been reported, but are areas that need further investigation and validation. The objective of this study is to evaluate the characteristics of glass FRP reinforcing bars and provide recommendations on the design and construction of concrete structures containing these bar types with regard to the areas described. The recently developed ACI 440 design guidelines were analyzed and modifications proposed.

Available in PDF, EPUB and Kindle. Book excerpt: Fiber Reinforced Polymers are by no means new to this world. It is only because of our fascination with petrochemical and non-petrochemical products that these wonderful materials exist. In fact, the polymers can be considered and used in the construction and construction repair. The petrochemical polymers are of low cost and are used more that natural materials. The Fiber Reinforced Polymers research is currently increasing and entails a quickly expanding field due to the vast range of both traditional and special applications in accordance to their characteristics and properties. Fiber Reinforced Polymers are related to the improvement of environmental parameters, consist of important areas of research demonstrating high potential and particularly great interest, as civil construction and concrete repair.

This book was released on 2013-05-15 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-quality and expedient repair methods are necessary to address concrete deterioration that can occur in bridge structures. Most infrastructure-related applications of fiber-reinforced plastics (FRPs) use hand layup methods. Hand layup is tedious, labor-intensive and results are sensitive to personnel skill level. An alternative method of FRP application is vacuum assisted resin transfer molding (VARTM). VARTM uses single-sided molding technology to infuse resin over fabrics wrapping large structures, such as bridge girders and columns. There is no research currently available on the interface developed, when VARTM processing is adopted to wrap fibers such as carbon and/ or glass over concrete structures. This chapter investigates the shear and flexural strength gains of a beam by carbon fiber cast on concrete using the VARTM method. The carbon fiber composite was made using Sikadur HEX 103C and low viscosity epoxy resin Sikadur 300. Tests were conducted to determine and document the gains of FRP rehabilitated beams applied by the VARTM method compared to the hand layup method of application. This newly introduced technique to repair and retrofit a simple span I-565 prestressed concrete bridge girder in Huntsville, Alabama, was implemented in the field within two days without any traffic interruption, and the field demonstration of this newly introduced technique to civil infrastructure is presented to the end.

Book excerpt: Fibre reinforced plastics are increasingly being used as replacements for steel reinforcement in concrete structures. The reinforcement can be untensioned, or it can be in the form of prestressing tendons. It is also suitable for gluing onto the outside of a structure to improve flexural or shear performance. This book provides up-to-date research results to give engineers confidence in their design methods.

This book was released on 2013-05-15 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-reinforced polymer (FRP) composite materials have been increasingly used in civil engineering applications in the past two decades. Their wide ranging use, however, is still not realized due to a few fundamental issues including high material costs, relatively short history of applications and the gaps in the development of established standards. Design safety requires that all possible modes and mechanisms of failure are identified, characterized, and accounted for in the design procedures. This chapter provides a review of the failure types encountered in structural engineering applications of FRP and the preventive methods and strategies that have been developed to eliminate or delay such failures. As part of preventive measures, various non-destructive testing (NDT) and structural health monitoring (SHM) methods used for monitoring FRP applications are discussed with illustrative examples.
