COMPUTATIONAL VALIDATION OF A FORCED-VIBRATION METHOD FOR STRUCTURAL HEALTH MONITORING OF LARGE-SCALE STRUCTURES, 2006

ABSTRACT

The field of structural health monitoring has been vastly growing in the civil structures discipline. The development of various techniques to monitor global and/or components changes has been the area of most growing. Most of these algorithms and techniques developed in this field have been validated using computer modeling. The focus of this paper was to develop and validate a sophisticated technique utilizing the transfer response function in detecting damages of large-scale complicated structures such as suspension bridges. The Vincent Thomas Bridge model was used in such validation. The technique was developed on a relatively complicated mathematical model of the Vincent Thomas Bridge. Structural changes were made to the stiffness of several members ranging from reduction in stiffness from 25 to 75 percent at several locations. This model proved to be very accurate in locating the structural changes (damage) on the bridge. This paper presents the results of this study.
