During　the　last　two　decades,　a　large　number　of　concrete　filled　steel　tubular　(CFST)　arch　bridges　have　been　built　in　China.　However,　the　seismic　response　of　the　CFST　structural　arch　rib　is　seldom　studied.　In　order　to　understand　the　seismic　response　of　CFST　arch　bridges,　based　on　the　similitude　law　of　artificial　mass,　a　CFST　arch　rib　model　scaled　1:10　of　the　Qunyi　Bridge　was　constructed　and　tested.　The　test　was　carried　out　on　the　earthquake　simulator　of　a　unique　triple　shaking　table　array　system　in　Fuzhou　University.　The　Sine　wave　and　several　recorded　ground　motion　waves　such　as　Taft　wave　and　artificial　waves　based　on　Chinese　code　were　adopted　to　evaluate　the　seismic　response　of　the　model.　The　waves　were　input　both　in　the　longitudinal　direction　and　in　the　transverse　direction.　The　testing　results　indicate　that　the　effects　of　transverse　seismic　responses　of　the　models　are　more　distinct　than　the　effects　of　longitudinal　seismic　ones　by　exciting　the　artificial　waves　of　E1　and　E2,　and　that　nevertheless　Taft　wave　are　reversed.　The　acceleration　magnification　in　crown　is　several　times　compared　to　arch　springing　while　in　uniform　excitations,　which　are　related　to　the　predominant　period.　Whereas,　the　axial　internal　force　and　bending　moment　in　arch　springs　will　be　increased　or　decreased　while　in　no-uniform　excitations　and　will　be　more　disadvantageous　to　the　model.　The　model　cannot　crack　or　fail　for　all　testing　cases,　which　reveal　that　CFST　arch　rib　structure　has　a　favorable　aseismic　performance.
