The　objectives　of　this　paper　are　to　integrate　the　structural　health　monitoring　(SHM)　technique　with　the　structural　seismic　analysis,　and　to　make　the　SHM　technique　serve,　benefit　and　promote　the　structural　seismic　analysis　integrally.　Therefore,　considering　a　concrete-filled　steel　tubular　arch　bridge　structure,　the　SHM　technique　is　used　to　calibrate　the　finite　element　(FE)　model　through　the　model-updating　scheme　to　minimise　the　structural　response　differences　caused　by　FE　model　errors.　Effects　of　model　updating　on　structural　seismic　responses　are　investigated　using　the　stochastic　vibration　analysis　approach.　It　is　observed　that　effects　of　model　updating　are　significant　on　structural　seismic　responses,　and　these　effects　may　become　more　evident　in　structural　nonlinear　dynamic　analysis.　Hence,　it　is　of　prime　importance　to　calibrate　the　FE　models　through　the　SHM　technique　for　seismic　evaluations　of　some　operational　critical　structures.
