Abstract：

An　ambient　vibration-based　seismic　evaluation　procedure　of　a　three　span　continuous　girder　bridge　is　presented.　The　procedure　includes　field　ambient　vibration　testing,　finite　element　(FE)　modeling,　selection　of　earthquake　ground　motion,　time　history　analysis　and　seismic　safety　evaluation　of　the　bridge.　Ambient　vibration　tests　were　carried　out　to　determine　the　dynamic　characteristics　of　the　bridge,　i.e.　eigenfrequencies,　mode　shapes　and　damping　ratios.　A　three-dimensional　FE　model　was　calibrated　based　on　the　ambient　vibration　test　results.　The　results　of　the　seismic　analysis　show　that　a　few　steel　members　have　to　be　strengthened　and　anchor　bolts　of　bearings　may　fail.　©　2003　Elsevier　Ltd.　All　rights　reserved.
