Description
We clarify seismic performance of an isolated bridge structure subjected to extreme ground motions during the 2011 off the Pacific Coast of Tohoku earthquake by carrying out nonlinear dynamic response analysis. Typical isolated bridge with a 1st natural period of more than 1.0sec located at Tokyo bay area is selected for analysis. The stiffness and damping coefficients of isolators installed in the bridge are identified by analyzing the transfer functions computed by the data of Fourier amplitudes for observed response data of decks and pier tops. Seismic responses of the bridge are clarified by comparing the simulated responses and observed ones based on identified equivalent stiffness and damping ratio of isolators.
