Book Description
The Nondestructive Evaluation (NDE) Section of the Lawrence Livermore National Laboratory has worked with the Federal Highway Administration (FHWA) and California Transportation Administration (Caltrans) to find solutions to inspection of aging bridges and highways. As an example of the magnitude of the aging infrastructure problem, the United States has over 500,000 miles of steel girders in bridges to inspect. In California, there are 26,000 bridges, approximately 3000 are steel, and of the steel bridges 1000 are fracture critical. Fracture critical bridges, those that will fail if a critical member fails, must be inspected routinely to ensure their safety. Corrosion and fatigue damage are two of the major problems that require routine assessment to determine extent of damage. We have developed ultrasonic methods for inspecting bridge pins, limited view computed tomography for inspecting bridge cables and cable anchors, and we are developing infrared imaging methods for inspecting bridge decks. We have proposed NDE solutions to a number of inspection problems that including: (1) evaluating concrete damage with ultrasonic, radiographic, and electromagnetic techniques; (2) assessing bridge scour with acoustic imaging technology; (3) monitoring crack growth with acoustic emission; and (4) determining moisture and salt accretion, intemal strain, and state of cure in concrete with embedded sensors,

Book Description
These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at the University of Washington, Seattle on July 30 to August 4, 1995. The Review was organized by the Center for NDE at Iowa State University, in cooperation with the Ames Laboratory of the USDOE, the American Society of Nondestructive Testing, the Department of Energy, the National Institute of Standards and Technology, the Federal Aviation Administration, the National Science Foundation IndustryiUniversity Cooperative Research Centers, and the Working Group in Quantitative NDE. This year's Review of Progress in QNDE was attended by approximately 450 participants from the US and many foreign countries who presented over 375 papers. The meeting was divided into 36 sessions with as many as four sessions running concurrently. The Review covered all phases of NDE research and development from fundamental investigations to engineering applications or inspection systems, and it included many important methods of inspection science from acoustics to x-rays. In the last several years, the Review has stabilized at about its current size. Most participants seem to agree it is large enough to permit a full-scale overview of the latest developments but still small enough to retain the collegial atmosphere which has marked the Review since its inception. The Proceedings are structured in a format to reflect the organization of the Review itself, producing a more logical organization for both the meeting and the present volume.
