Description
We investigated an isolated bridge subjected to long-period ground motions during the 2011 off the Pacific Coast of Tohoku earthquake. We identified modal parameters of the bridge by using multi-degree-of-freedom systems model consisting of superstructures, piers, and pile foundations. The natural frequency and damping coefficients of the bridge were identified by analyzing the transfer functions computed by the observed acceleration data of decks, pier top, ground surface and pile foundation, compared with the theoretical transfer function.
