Description
For the Tsurumi Tsubasa cable stayed bridge, this study revealed the dynamic characteristics based on analyses of the seismic records by the aftershocks of the 2011 off the Pacific coast of Tohoku earthquake. We estimated the dynamic characteristics of natural frequencies and vibration modes by spectral analyses of the recorded accelerations. We identified modal parameters of the bridge by using multi-degree-of-freedom- system model consisting of super-structures, piers, and foundations. The natural frequencies and damping coefficients of the bridge were identified by analyzing the transfer functions of girder and tower records with respect to the foundation record, compared with the theoretical transfer functions.
