| Abstract: | The direct displacement-based anti-seismic design method for base-isolated co ntinuous girder bridges is proposed, including establishing the elastic design d isplacement-response spectra, and presenting the design procedure. This design procedure is used to study the symmetrical and asymmetrical base-isolated conti nuous bridges; and the design results of respective examples are analyzed and ch ecked by modal analysis and dynamic inelastic time-history analysis to clarify the rationality of the design results. |
