Abstract
Bridge scour monitoring using fixed instrumentation is a good way for the owner to be warned of imminent failure and take appropriate action before exposing the public to undue risk. The paper shows an easy way to predict imminent failure of bridges by installing a motion sensor on the bridge. A large scale lab test is described in the paper, and a relationship between the natural frequency of the bridge and the scour depth is presented. It is shown that the natural frequency of the simulated bridge-foundation system changes with time and becomes drastic near failure.
