Structural　displacement　amplification　factor　(DAF)　is　the　key　factor　in　seismic　design,　which　is　used　to　predict　maximum　inelastic　deformations　of　structures　under　earthquake　excitation.　However,　DAF　has　not　been　introduced　in　the　current　Chinese　seismic　design　code.　In　this　paper,　15　RC　frame　buildings　which　were　3-,　5-,　8-,　10-,　12-story　buildings　in　different　seismic　fortification　intensity　VI,　VII,　VIII　were　designed　according　to　the　Code　for　Seismic　Design　of　Buildings　GB　50011-2010.　The　FE　models　of　these　buildings　were　modeled　and　structural　seismic　response　was　analyzed.　Shaking　table　test　of　a　RC　frame　structure　has　been　accomplished　and　the　FE　models　were　verified　and　validated.　The　＇demand＇　values　of　the　structural　DAF　of　these　RC　frames　were　evaluated　by　the　dynamic　capacity　spectrum　method,　and　the　analysis　results　were　compared　with　that　analyzed　by　the　traditional　static　capacity　spectrum　method.　For　the　designed　RC　frames　in　the　seismic　fortification　intensity　VI,　VII,　VIII　zones,　the　ranges　of　demand　values　of　structural　DAF　are　0.51-1.91,　0.49-1.93,　and　0.56-2.24　respectively　when　they　are　under　fortification　earthquakes.　The　ranges　of　demand　values　of　structural　DAF　are　1.18-4.05,　1.33-3.45,　and　1.42-2.66　respectively　when　they　are　under　rare　earthquakes.　The　overall　yield　of　the　codified　designed　RC　frames　under　fortification　earthquakes　has　not　occurred.　And　it　is　shown　that　the　Chinese　seismic　design　code　is　conservative.　©　2016,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
