In　order　to　explore　the　seismic　response　of　a　self-anchored　suspension　bridge　when　considering　the　collision　effect　under　the　action　of　pulse-like　ground　motions,　a　self-anchored　suspension　bridge　with　single　tower　was　taken　as　a　prototype　to　design　the　test　model　with　a　reduced　scale　of　1:20,　and　three　near-fault　pulse　seismic　waves　of　different　pulse　periods　were　selected　to　perform　comparative　tests　under　uniform　excitation　and　traveling　wave　excitation　on　a　multiple-earthquake-simulation-shake-table　system.　According　to　the　test　results,　the　collision　effect　has　significantly　aggrandized　the　deformation　of　side　pier　bottom　but　reduces　the　displacement　response　of　the　support　in　varying　degrees;　the　collision　effect　at　ends　of　the　model　bridge　first　heightens　and　then　recedes　as　collision　gap　widens　while　the　traveling　wave　excitation　has　intensified　collision　at　bridge　ends　so　that　the　collision　effect　significantly　amplifies　the　deformation　of　side　pier　bottom　and　deformation　of　main　tower　bottom;　the　closer　the　pulse　period　of　pulse-like　ground　motions　is　to　the　basic　cycle　of　model　bridge　girder,　the　more　intense　the　collision　effect　and　the　more　significant　amplifying　effect　on　the　deformation　of　side　pier　bottom　and　main　tower　bottom,　but　less　effect　on　the　reduction　of　support　displacement.　Therefore,　factors　such　as　collision　effect,　traveling　wave　effect　and　pulse　characteristics　of　ground　motions　should　be　considered　at　seismic　or　aseismic　design　of　a　self-anchored　suspension　bridge.　The　findings　will　provide　references　for　studying　bridge　structure　collision　response.　©　2019,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
