In　the　present　study,　the　dynamic　property　of　a　specially　shaped　hybrid　girder　bridge　with　concrete-filled　steel　tube　(CSFT)　arches　is　investigated　based　on　experimental　and　numerical　methods,　especially　under　moving　vehicles.　Before　the　inauguration　of　this　bridge,　a　dynamic　field　test　was　conducted.　A　refined　three-dimensional　finite　element　model　is　built　to　represent　the　complex　structural　mechanic　property　of　the　bridge.　The　vehicle-bridge　coupled　vibration　(VBCV)　model　with　a　16　DOF　vehicle　model　is　established　to　simulate　the　dynamic　behavior　of　the　bridge　with　moving　vehicles.　The　FE　model　is　updated,　and　the　VBCV　model　for　the　bridge　is　verified,　taking　advantage　of　the　aforementioned　measured　data.　The　result　indicates　that　the　proposed　VBCV　numerical　model　can　closely　reproduce　the　measured　response　and　can　be　used　to　simulate　the　dynamic　behavior　of　the　bridge　under　various　conditions.　The　impact　effect,　ride　and　pedestrian　comfort,　and　related　parameters　analysis　for　the　bridge　with　moving　vehicles　are　studied　by　numerical　simulations　and　experimental　tests.　The　results　indicate　that　the　impact　factor　formula　from　design　standards　significantly　underestimates　the　dynamic　impact　effect,　which　may　result　in　an　unfavorable　influence　on　the　bridge　safety.　Several　conclusions　are　drawn　for　this　bridge,　and　further　research　that　is　needed　for　this　new　bridge　type　is　discussed.　(C)　2015　Elsevier　Ltd.　All　rights　reserved.
