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 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 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.

Available in PDF, EPUB and Kindle. Book excerpt: Thanks to their low density and tailored properties, polymer matrix composites are attractive candidates for a large number of industrial applications ranging from aerospace to transportation and energy. However, the behaviour of polymer-based materials is strongly affected by a number of environmental factors. Environmental Degradation in Industrial Composites provides vital information on the effects of environmental factors such as temperature, liquid and gas exposure, electrical fields and radiations, and how micro- and micromechanical calculations during design and manufacture must take these effects into account. The book concludes with reviews on standard and specific testing methods for the various environmental factors and their combinations, helping mechanical/materials engineers and specifiers to predict possible changes due to environmental conditions. Each chapter is supplemented by industrial case studies to help in the understanding of degradation of composites in real life situations.This book will help you to...* Understand how environmental factors lead to degradation effects in polymer matrix composite structures* Build these factors into calculations when predicting the part performance and lifetime of structures* Compare real-life situations from case studies with your predicted results* Predict probable composite behaviour with greater accuracyThis book will help you to...* Understand how environmental factors lead to degradation effects in polymer matrix composite structures* Build these factors into calculations when predicting the part performance and lifetime of structures* Compare real-life situations from case studies with your predicted results* Predict probable composite behaviour with greater accuracy

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 2007 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide-flanged concrete girders are increasingly being used for highway bridges in Wisconsin. The objective of this research was to understand the state of the art of non-metallic SIP forms and to develop design guidelines and performance specifications that can be used locally for the construction of highway bridge decks. Four major types of stay-in-place (SIP) forms using fiber reinforced concrete (FRC) or fiber reinforced polymer (FRP) materials were investigated: fiber reinforcements, grid reinforcements, bar reinforcements and pultruded profiles. The results were used to develop a model design and construction specification for non-structural, non-metallic, SIP forms in highway bridge decks.

Download or read book Behavior of 50 Year Old Prestressed Concrete Bridge with Fiber Reinforced Polymer Deck Replacement written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges B-0071, and B-0171 in Hamilton County, Ohio have been in service for about fifty years. They are short span bridges with prestressed concrete girders. Until late 2001, they had conventional reinforced concrete decks. On November third of that year the ribbon was cut to reopen the bridges, now with Fiber Reinforced Polymer Decks. One of the bridges also had the girders replaced. These are the only bridges in existence that have FRP decking on concrete girders. The Hamilton County Engineers Office contracted with the Civil Engineering Department at the University of Cincinnati to perform research on these bridges. Information gained from this research will seek to confirm the safety of the new technology, approve construction and design techniques with reference to the FRP deck, and determine overall performance of the bridge to provided understanding of the system. The 50-year-old prestressed concrete girders were subjected to destructive load testing. The girders showed little loss of strength or stiffness from aging. The information on the performance of the girders was used in the analysis of the bridge system. Two of the bridges were subjected to nondestructive load testing. A three-dimensional finite element model was then created to replicate the performance of the bridges. Data from the bridge tests provided enough information to create an accurate model of the bridge girders, but not the deck. Using the finite element model, a Load Rating was performed. The bridges were found to be sufficiently strong to resist the loads that may be applied to them. The deck showed no signs of separation from the concrete girders as was previously suspected. The bridge system acted as a fixed end beam because of the semi-integral end abutments for the range of loads tested. The deck was not adding any strength tot the girders through composite action. The load transfer from one girder to another was not provided by the deck as was assumed in the design process, but by the concrete diaphragms used for lateral stability. Further testing will be needed to understand the deck performance better so that a full bridge analysis may be performed.
