Near-fault　pulse-type　(NFPT)　ground　motion　is　characterized　by　pronounced　velocity　pulse　effects.　Its　velocity　pulse　period　is　typically　greater　than　1　s,　and　has　a　large　influence　on　the　seismic　response　of　long-period　bridges.　However,　few　quantitative　studies　about　the　influence　of　the　pulse　parameters　have　been　reported.　In　this　work,　that　influence　-　namely,　velocity　pulse　period　(VPP),　velocity　pulse　amplitude　(VPA),　and　velocity　pulse　number　(VPN)　-　on　the　seismic　response　of　a　long-period　bridge　was　studied.　A　1/15-scale　model　was　designed　and　a　synthetic　method　was　introduced　to　obtain　artificial　NFPT　ground　motions.　Then,　a　series　of　shaking　table　tests　and　numerical　simulation　analyses　were　conducted.　The　results　show　that　the　synthetic　method　can　be　used　to　obtain　artificial　NFPT　ground　motions　for　different　pulse　parameters.　The　pulse　effect　can　significantly　increase　the　seismic　response　of　the　model　bridge.　The　response　increases　as　VPA　increases.　In　the　case　of　the　increasing　VPP,　the　response　first　increases　and　then　decreases.　It　may　be　greater　when　the　VPP　is　close　to　the　natural　vibration　period　of　the　model.　The　displacement　response　spectrum　value　can　be　used　to　predict　the　influence　of　the　VPN.　A　larger　spectrum　value　can　induce　a　larger　response.
