As　a　new　kind　of　bridge　structure,　multi-tower　self-anchored　suspension　bridge　(MSSB)　has　complicated　mechanical　characteristics.　So　far,　the　research　on　dynamic　performance　of　MSSB　is　limited　to　theoretical　and　numerical　simulation.　Based　on　the　first　three　shaking　table　system　in　China,　shaking　table　test　of　MSSB　is　carried　out.　The　modal　test　and　seismic　excitation　test　show　that　the　performance　of　fundamental　mode　shape　is　anti-symmetric　vertical　bending　vibration　of　girder,　coupling　with　longitudinal　bending　vibration　of　middle　tower.　Seismic　response　of　middle　tower　is　greater　than　side　towers.　At　last,　3D　finite　element　model　of　test　specimen　is　established　and　test　process　is　numerical　simulated　by　FEM.　Simulated　result　is　agreed　well　with　test　record.
