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.

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.

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.

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 accuracy 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 accuracy

This book presents the analysis and design of fiber-reinforced polymer (FRP) bridge decks, which have been increasingly implemented in rehabilitation projects and new construction due to their reduced weight, lower maintenance costs, and enhanced durability. It compiles the necessary information, based primarily on research by the authors, to facilitate the development of standards and guidelines for using FRP decks in bridge designs. The book combines analytical models, numerical analyses, and experimental investigations, which can be applied to various design formulations. It also, for the first time, offers a complete set of design guidelines.
