To　consider　the　influence　of　expansion　joint　parameters　on　the　vehicle-bridge　coupling　dynamic　response,　the　equivalent　contact　force　and　displacement　models　were　proposed　by　analyzing　the　process　of　wheel　passing　through　the　joint.　The　vehicle-bridge　coupling　dynamic　response　analysis　model　considering　the　impact　of　expansion　joint　parameters　was　established　by　the　local　mode　extraction　method　and　the　modal　synthesis　method.　Based　on　the　Matlab　platform,　the　analysis　procedure　of　vehicle-bridge　coupling　vibration　considering　vehicle　passing　expansion　joint　and　the　numerical　calculation　method　were　constructed.　The　vehicle-bridge　coupling　dynamic　response　analysis　method　considering　the　expansion　joint　parameters　was　verified　by　the　field-testing　results　of　a　simple-supported-to-continuous　girder　bridge.　The　results　show　that　the　errors　between　the　numerical　results　and　the　field-testing　results　of　the　peak　values　of　the　acceleration　and　displacement　response　of　the　expansion　joints　and　the　main　beam　are　within　7%,　indicating　that　the　proposed　analysis　method　can　be　used　to　analyze　the　vehicle-bridge　coupling　dynamic　response　considering　the　impact　of　expansion　joint　parameters.　©　2022,　Editorial　Department　of　Journal　of　Southeast　University.　All　right　reserved.
