Integration of NDT Results into the Evaluation of Distressed Structures
Publication: Forensic Engineering 2009: Pathology of the Built Environment
Abstract
Nondestructive test methods (NDT) are available for the assessment of many types of defects in existing structures including: the evaluation of reinforcing steel corrosion, determination of defect location, accurate assessment of the member sizes, and reinforcement locations. The use of these methods has increased as engineers and owners become aware of their capabilities. However, recent experiences have suggested that the integration of the NDT results into the evaluation process is lagging, and often the results of the NDT program end up as little more than report filler. Worse, the lack of NDT verification can result in incomplete or erroneous conclusions about the structure. Integration of NDT results into the evaluation process requires an understanding of both the output of the test methods and how the results impact structural performance. The successful integration of NDT results into the evaluation process is described.
