摘要

Unexpected collapses and near collapse of bridges during the 1999 Chi-Chi earthquake underline the need for effective structural monitoring. Periodic structural condition monitoring of bridge structures is necessary to ensure that they provide a continued and safe service. A systematic study of typical bridges is needed, focusing on identifying elastic analytical models that will incorporate the existing state of bridge. To establish dynamic monitoring as a routine bridge inspection method, the soil-structure model of these two bridges are established and compared theoretically and experimentally.
