| 摘要： | The major objective of this report is to evaluate various non-destructive testing/evaluation (NDT/NDE) technologies for use on bridge columns that have been retrofitted with FRP-type jackets. Suitable and/or potentially suitable techniques for practical applications are identified, and promising techniques that could benefit from additional research prior to use in engineering applications are assessed. For each technology, the inherent physical principles and application characteristics are analyzed and their advantages and disadvantages are compared in order to determine whether each method could be used to detect damage and defects in the jacketed bridge columns. The most promising NDE methods are identified and corresponding application procedures are then presented. This report focuses solely on the application of NDE technologies to bridge columns, and therefore, recommendations and conclusions herein may differ from those discovered for other applications. / NOTE: Technical rept. / Supplementary Notes: Sponsored by the Multidisciplinary Center for Earthquake Engineering Research, Buffalo, NY., and the Federal Highway Administration, Washington, DC. / Availability Note: Available on CD-ROM and in color paper copy only.
