Impact Load Method for Structural Assessment of Piers and Bridges

Abstract

NCEL examined the Impact Load Method (ILM) to elicit a response from bridges and piers as a means of structural assessment. Stiffness changes were detected that were correlated to loss of structural function from material damage and deterioration. Parametric studies were performed on a one-third scale model pier and a highway bridge using finite element modeling that was verified by ILM tests. Studies showed that the ILM is sensitive to the loss of cross section in pier and bridge decks and well as to the loss of pile support....
