Updating of finite element model of cable stayed bridges for improved dynamic characteristization and active seismic response control implementation

Abstract

The present work deals with the model updating of two cable stayed bridges viz the Quincy Bayview bridge of Illinois USA and the Bill Emerson Memorial Bridge Missouri USA and subsequently studies on active response of these bridges subjected to seismic excitations have been carried out The finite element models for both the bridges have been updated so as to reproduce the experimentally observed modal characteristicsto the closest possible extent
