A　suspend-dome　structure　is　a　new　prestressed　steel　system,　which　is　suitable　for　the　roof　of　a　big　span　structure.　The　experiment　study　on　the　anti-seismic　performance　of　the　new-type　large　span　suspend-dome　of　badmiton　Gympasiwm　for　2008　Olympic　Games　is　a　guarantee　to　a　large-scale　public　building.　The　dynamic　feature　and　vibration　table　experiments　of　a　9.3　m　suspend-dome　structure　model　were　conducted　through　the　multiple　vibration　table　array　system　in　Beijing　University　of　Technology.　Dynamical　features　of　the　model　were　tested.　The　responses　and　rules　of　acceleration,　displacement,　stress　of　the　structure,　and　force　of　cable　under　the　earthquake　were　obtained.　Results　show　that　the　structure　has　closely　distributed　modes,　and　has　good　anti-seismic　performance　under　strong　earthquakes　at　a　magnitaude　of　eight.
