This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, fiber-reinforced polymer (FRP) deck systems have emerged as a viable alternative to conventional systems, namely reinforced-concrete slabs. The use of such systems to replace existing, deteriorated bridge deck systems offers both economic benefits and improved performance. The economic advantages are possible for a number of reasons: since such composite systems are lighter, considerable savings are realized by reduced transportation costs (several deck systems can be transported on one truck); erection costs will be less as relatively light cranes can be used to install the decks; and construction time is reduced, which eliminates long traffic delays. Due to the high resistance of FRP deck systems to environmental effects and corrosion attack, the long- term performance is also expected to be improved significantly, leading to lower maintenance and longer service life.

This book was released on 2004 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This investigation studied the structural performance of FRP composite materials in bridge decks through in-place load tests and analytical studies. Two multi-panel bridge decks were studied: Saint Francis Street Bridge consisting of a deck built with four glass FRP (GFRP) honeycomb panels, whereas Waters Street Bridge consists of nine FRP-RC panels. The performance of the two bridges was monitored by load tests for over three to four years. The main objectives of this investigation were: to examine the deflection data in service that can be correlated to allowable deflections; to estimate if there is any stiffness degradation that can indicate distress in the deck; to compute the load fraction distribution between panels based on experimental data and attempt the load rating using the load test results"--Introduction, leaves 2-3.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In an effort to better understand the performance of bridges with fiber reinforced polymer (FRP) composite decks, four different deck systems were installed in a 207-meter, three-lane, five-span bridge in Dayton, Ohio. The spans range from 40 to 44 m, and the bridge consists of six steel girders. The span lengths and large number of panels created a unique opportunity to evaluate the response of four common FRP bridge deck systems under identical traffic and environmental conditions. Over a six-year period, the performance of the bridge and its components were monitored through field documentations, long-term continuous monitoring of key responses, controlled static and dynamic truck load tests conducted on a regular basis, and multi-reference modal tests performed in conjunction with the truck load tests. The measurements from nearly 300 sensors allowed a detailed evaluation of critical design issues such as the behavior of FRP panel-steel girder connections and connections between FRP panels, impact factor and distribution factors for bridges with FRP decks, thermal characteristics of FRP panels versus conventional reinforced concrete decks, critical role of thermal behavior of FRP panels on the overall performance, level of composite action, and serviceability issues for bridges with FRP decks. Based on the presented information, a number of recommendation for improved behavior are made.

This book was released on 2009 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the United States, about 27% of the bridges are classified as structurally deficient or functionally obsolete. Bridge owners are continually investigating methods to effectively retrofit existing bridges, or to economically replace them with new ones. Modern composite materials for structural applications, at one time only in the domain of aerospace engineering, are increasingly making their way into civil engineering applications. In addition to retrofitting current concrete and steel structures using FRP sheets or plates, a great deal of work is being conducted to develop versatile, fully-composite structural bridge systems. To reduce the self-weight and also achieve the necessary stiffness, sandwich panels are usually used for bridge decks. However, due to the geometric complexity of the FRP sandwich, convenient methods for bridge design have not been developed. The present study aims at developing finite element modeling techniques for sandwich structures. Parametric studies are carried out with the objective of developing equivalent elastic properties, which would be useful parameters in design. A distinction is made between in-plane and out-of-plane behavior, and properties are derived accordingly. The performance of the sandwich, such as the interface stress between the flange and wearing surface can be evaluated. Therefore, through finite element modeling, optimization can be achieved in order to minimize the interface stress. The contribution of stiffness of the wearing surface to structural performance, a factor which is not usually accounted for in typical design procedures, is also examined. An effort is also made to analyze the temperature effects on the structure's performance. A conceptual approach aimed at studying the thermal performance of the panel due to both uniform and gradient temperature variations is presented"--Technical report documentation page.

This book was released on 2003 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decks manufactured with fiber-reinforced polymer (FRP) composite materials are used in highway bridges. A performance evaluation of FRP composite decks subjected to simulated traffic loads that induce repetitive stress cycles under extremely high and low temperature is presented. Fatigue testing of three FRP composite bridge deck prototypes and one FRP-concrete hybrid bridge deck prototype under two extreme temperature conditions: -30 C ( -22 F), and 50 C (122 F) was conducted. The fatigue response of the deck prototypes was correlated with the baseline performance of a conventional reinforced concrete deck subjected to similar test conditions. Design loads were applied simultaneously at two points using servo-controlled hydraulic actuators specially designed and fabricated to perform under extreme temperatures. Quasi-static load-deflection and load-strain characteristics were determined at predetermined fatigue cycle levels. No significant distress was observed in any of the composite deck prototypes during ten million load cycles. The effects of extreme temperatures and accumulated load cycles on the load-deflection and load-strain response of FRP composite and FRP-concrete hybrid bridge decks are discussed based on the experimental results.

This book was released on 2013-05-15 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The primary objective of this chapter is first to introduce and demonstrate the application of thermoplastic (woven glass reinforced polypropylene) in the design of modular fiber-reinforced bridge decks, and next the development of jackets for confining concrete columns against compression and impact loading. The design concept and manufacturing processes of the thermoplastic bridge deck composite structural system are presented by recognizing the structural demands required to support highway traffic. Then the results of the small-scale static cylinder tests and the impact tests of concrete columns are presented, demonstrating that thermoplastic reinforcement jackets act to restrain the lateral expansion of the concrete that accompanies the onset of crushing, maintaining the integrity of the core concrete, and enabling much higher compression strains (compared to CFRP composite wraps) to be sustained by the compression zone before failure occurs.

This book was released on 2015 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber Reinforced Polymers (FRP) is a newly developed composite type of material which have many advantages over conventional materials (concrete and steel) like light weight, non-corrosive nature, design flexibility and quick installation. Due to its superior thermo-mechanical properties, it has emerged as one of the best economical method to strengthen and repair reinforced concrete bridges that were damaged each year due to various reasons like structural deterioration over time, fire accidents, corrosion of steel reinforcement and over height vehicle collision. This research aims to evaluate the long term performance of FRP strengthened bridge components with the help of Pull-Off tests. It will also recommend certain guidelines to be followed during the time of repair for the better performance of FRP. In this study a total of eight concrete bridges in the DFW area, that were damaged in the past and strengthened using Carbon Fiber Reinforced Polymer (CFRP) wrap were identified and later Pull-Off tests were performed on selected test locations of the bridge components as per the specifications of ASTM D7522/D7522M (2009) .After evaluation of the Pull-Off test results it was determined that the overall performance of FRP is good.
