Assessment of scour of foundation with dynamic tests

Scour of foundations is a major issue for the structural safety of existing bridges, hence its monitoring is of paramount importance. Dynamical tests on the structure provide appealing tools for assessment and monitoring. Two different approaches have been applied as potential tools for monitoring scour of foundations on the basis of measurements of traffic induced vibrations. One approach is based on modal identification for bridge spans, while the other is based on the observation of the dynamic response of pier foundations.

 

Example: Modal shapes and frequencies: a) before retrofitting of Pier #2; b) after retrofitting of Pier #2

In cooperation with prof. Donato Sabia
