Damage localization accuracy as a function of model uncertainty in the I-40 bridge over the Rio Grande

摘要

Abstract: The impact of model uncertainty on the damage localization accuracy of a nondestructive damage detection technique when applied to a full-scale plate-girder bridge is assessed. First, a nondestructive damage detection algorithm to localize damage from a few mode shapes of structures is outlined. Next, damage localization exercises are performed for a real highway bridge (on the US Highway I-40) located in Bernalillo County, New Mexico, USA. Finally, the accuracy of damage localization results for the test structure is assessed as a function of the model uncertainty of the damage localization procedure for the structure. !22
