"Field validation of fiber reinforced polymer (FRP) bridges through load testing provides a means of measuring the performance of a bridge over time. Non-contact optical surveying equipment is one such method that can be utilized to measure the deflection of bridges under a static truck load. This thesis looks at monitoring bridges over time that have been both strengthened and constructed with FRP technologies. Five structurally deficient Missouri bridges have recently been retrofitted with FRP technologies with the intent to validate the overall in-situ performance. Testing focused on Nondestructive testing (NDT) techniques as a means of conducting these tests without damaging the existing structures. Static load testing was conducted and the results of the pre-strengthened and post-strengthened deflections have been used to evaluate the structural health over time"--Abstract, leaf iii.

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.

The result of the authors' 40 years of experience in durability testing, this book describes the advanced testing methodology based on the viscoelasticity of matrix polymer. After a short introduction to the viscoelastic behavior of fiber-reinforced plastics, the text goes on to review in detail the concepts of static, fatigue and creep strengths in polymer composites. An application-oriented approach is adopted such that the concepts developed in the book are applied to real-life examples. Indispensable information for materials scientists and engineers working in those industrial sectors is concerned with the development and safe use of polymer composite-based products.

"Crack development in reinforced concrete (RC) structures is common in elements such as bridge decks. However, these cracks can impose significant problems over time, because they allow chlorides from deicing chemicals to infiltrate concrete which will then corrode steel bars as RC structures are exposed to harsh weather. In the last decade, composite reinforcement systems are internally or externally applied to concrete structures instead of traditional steel reinforcing bars, or to strengthen concrete elements in flexure and shear. However, studies regarding the long-term durability performance of composite reinforcement systems is limited. Therefore, in order to popularize the application of these systems, it is necessary to study the long-term properties and behaviors of concrete members reinforced with composite materials. This study includes three topics: 1. Long-term durability of concrete panels reinforced with steel and glass reinforced polymer (GFRP). The main objective of this study is to investigate the mechanical properties of GFRP bars extracted from concrete panels after seven plus years of field exposure and examine any microscopic damage to the GFRP fiber and/or matrix resin; 2. Durability of concrete elements reinforced with Steel Reinforced Polymer (SRP). The key purpose of this study is to assess the bond behavior of SRP-to-concrete systems and provide durability study of SRP strengthening systems to supplement ACI 440; 3. Assessment of existing FRP bridge structures exposed to field conditioning. This study focuses on investigating the physical inspection for the existing FRP bridges in Rolla, MO and to characterize GFRP bars extracted from Southview Bridge (MO), Walker Bridge (MO), and Sierrita de la Cruz Bridge (TX) and surrounding concrete after several years of service"--Abstract, page iii.

The overarching goal of this study was to perform a comprehensive evaluation of various issues related to the strength and serviceability of the FRP deck panels that are available in the industry. Specific objectives were to establish critical limit states to be considered in the design of FRP deck panel, to provide performance specifications to designers, and to develop evaluation techniques for the deck panels in service. Two different FRP panels were studied during the research project: a sandwich panel and a pultruded panel. The sandwich panel was initially selected for the rehabilitation case study bridge. However, for a variety of reasons outside of the scope of this study, both the sandwich panel and the initial case study bridge were dropped from consideration. A new case study bridge was selected, and new proposals from FRP deck manufacturers were solicited. At that time, the pultruded deck was selected. Analysis and experimental results related to both FRP deck panels are included in this report, as information from both decks is relevant to the overarching goal of this study. In November 2009, Sugar Creek Bridge became the first bridge in Indiana to be rehabilitated with an FRP bridge deck. An extensive study, including literature review, analysis, and load tests, suggest that the installed deck should perform well, with web buckling as the ultimate failure mode at a factor of safety of 5. Deflection limits, generally an issue with FRP decks, are satisfied with the installed deck. Meanwhile, some combination of acoustic emission methods, infrared thermography and a newly developed traveling truck deflection method show promise for non-destructive evaluation of the deck in-situ and identification of damage such as delamination of the wearing surface or web buckling. However, such methods have shown variability and could be prohibitively labor-intensive. Therefore, further evaluation is needed if such methods are to be pursued.
