The seismic response of a base-isolated bridge is investigated with the help of acceleration data recorded during four moderate to small earthquakes. It is observed that the dynamic behavior of the bridge is not typical of base-isolated bridges as some of the transverse side-stoppers obstructed the movement of isolation bearings. Examination of the recorded transfer functions revealed that the dynamics...
Identification of system parameters with the help of records made on a base-isolated bridge during earthquakes, provides an excellent opportunity to study the performance of various components of such a bridge system under these loading conditions. This study utilizes a two-stage system identification methodology for identifying the modal and structural parameters of base-isolated Yama-age bridge...
