  • Patent number: 8781804
    Abstract: Provided is a method of estimating a load carrying capacity of a bridge. The load carrying capacity estimation method includes the steps of: estimating a mode coefficient of the bridge using an acceleration signal obtained from an accelerometer that is installed in the bridge; updating an analysis model of the bridge using the estimated mode coefficient; and estimating a rating factor of the bridge by applying a dead load and a design live load to the updated analysis model.
