This　paper　makes　use　of　the　multiple　sub-table　cordwood　system　to　conduct　a　study　on　the　shaking　table　test　of　a　three-span　irregular　CFST　arch　bridge.　The　test　completed　uniform　excitation　case　and　traveling　wave　excitation　case　that　contains　longitudinal　input,　transverse　input,　vertical　input,　transverse　and　longitudinal　combinatorial　input,　and　transverse　and　vertical　combinatorial　input.　The　seismic　response　and　response　characteristics　of　acceleration,　displacement,　internal　force　of　suspenders　and　tie　bars,　and　strain　of　structure　under　earthquake　excitations　were　gained,　which　could　provide　test　data　and　basis　to　evaluate　the　seismic　performance　of　this　CFST　arch　bridge　or　other　similar　structural　system　design.
