The　previous　seismic　disaster　indicates　that　the　traditional　masonry　infill　wall　was　easy　damaged　during　earthquake.　The　traditional　masonry　infill　wall　not　only　increases　the　load　of　the　main　structure　but　also　injures　people　during　collapsing.　So　a　new　aseismic　structure　system　with　hanging　prefabricated　infill　plate　was　proposed.　The　dynamical　characteristic　of　frame　structure　with　hanging　prefabricated　infill　plate　was　analyzed.　By　simplifying　the　hanging　prefabricated　infill　plate　as　a　rigid　bar,　the　free　vibration　equation　of　aseismic　structure　system　with　hanging　prefabricated　infill　plate　was　established.　Furthermore,　the　influence　of　main　parameters　on　the　natural　frequency　of　the　whole　aseismic　structure　system　with　hanging　prefabricated　infill　plate　was　discussed.　Through　the　vibration　table　test　and　finite　element　simulation,　the　aseismic　effect　of　hanging　prefabricated　infill　plate　was　studied.　The　influence　factors　and　application　conditions　of　aseismic　structure　system　with　hanging　prefabricated　infill　plate　were　discussed.
