NONDESTRUCTIVE INSPECTION OF STEEL (PHASE I)

This final report (Phase I) discusses the nondestructive inspection methods used by the California Department of Transportation, Transportation Laboratory for the inspection of steel bridge structures during construction. These methods are radiography, ultrasonic, magnetic particle, and liquid penetrant. It concludes that no one method by itself will provide the assurance of a structurally sound bridge. Although the Transport Laboratory will be unable to complete Phase II of this project, it feels it is important enough to recommend it be performed by others. Additional information is included in this report on acoustic emission and the acoustic crack detector and magnetic crack definer developed by Southwest Research Institute. The information contained herein is of an informative nature similar to a "state of the art" type report. /Author/
