Evaluating Damage Detection in Bridges

by David F. Mazurek, U.S. Coast Guard Acad, New London, United States,



Document Type: Proceeding Paper

Part of: Engineering Mechanics

Abstract:

Several researchers have recently considered using vibration monitoring of highway bridges as a means for detecting structural deterioration. Results to date have demonstrated that the concept of tracking the global modes of a structure is effective both in identifying the development of significant damage and in isolating its location. This paper describes an analytical tool for assessing the influence of damage at any location to the flexural modes of vibration in a simply-supported beam.
