"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.

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.

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 chapter first reviews current structural applications of fiber-reinforced polymer (FRP) composites in bridge structures, and describes advantages of FRP in bridge applications. This chapter then introduces the design of a hybrid FRP-concrete bridge superstructure, which has been developed at The University at Buffalo for the past ten years, and discusses structural performance of the superstructure based on extensive experimental and analytical studies.

This book examines current issues of fiber reinforced polymer (FRP) composites in civil infrastructure. The contents of this book are divided into two parts. The first part engages topics related to durability and service life of FRP composites and how they contribute to sustainability. The second part highlights implementation and applications of the FRP composites with an emphasis on bridge structures. An introductory chapter provides an overview of FRP composites and its role in a sustainable built environment highlighting the issues of durability and service life followed by a current review of sustainability in infrastructure design.​

Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridges Describes the response of structures to dynamic actions that have attracted growing attention in recent years Highlights features of the different structural components and their interaction in the entire structural system Presents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.

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 reviews the progress made worldwide in the use of fibre reinforced polymers as structural components in bridges until the end of the year 2000. Due to their advantageous material properties such as high specific strength, a large tolerance for frost and de-icing salts and, furthermore, short installation times with minimum traffic interference, fibre reinforced polymers have matured to become valuable alternative building materials for bridge structures. Today, fibre reinforced polymers are manufactured industrially to semi-finished products and complete structural components, which can be easily and quickly installed or erected on site.
