Abstract: A nondestructive crack detection (NCD) scheme to locate a crack and estimate the crack size by using changes in the modal parameters of a class of bridges is presented in this paper. First, the theory underlying a ...

Abstract: The impact of model uncertainty on the damage-prediction accuracy of a nondestructive damage-detection technique when applied to a model plate girder is assessed. First, a damage-detection algorithm to locate and size ...

Abstract: The results of numerical simulations to test a method to locate and estimate the severity of damage in a structure in the blind mode, by using the simulated data from a four-story steel frame structure analyzed at the Univ. ...

Abstract: The Lavic Road Bridge in San Bernardino County, California, was severely damaged during the October 16, 1999, Hector Mine Earthquake (7.1 Mw). The earthquake epicenter was approximately 16 km (10 mi) south-southwest of the ...
