Paper Abstract

In this paper, a robust algorithm to detect and localize damage in full-scale plate-girder bridges by utilizing modal response parameters of undamaged (as-built) and damaged structures is presented. In the first part, a damage detection algorithm which yields information on the location of damage directly from changes in mode shapes of structures is outlined. In the next part, the algorithm is implemented to detect and localize damage in a real highway bridge (on the US Highway I-40) located in Bernalillo County, New Mexico, USA. In this damage detection exercise, pre-damage and post-damage modal parameters of only a single mode measured from the test structure are utilized to localize the damage.
