“Capacity”　value　of　structural　displacement　amplification　factor　(DAF)　is　a　key　factor　in　seismic　design,　since　it　can　be　used　to　estimate　the　maximum　inelastic　deformations　developed　in　severe　earthquakes,　and　to　estimate　the　minimum　building　spacing　to　avoid　the　collapse　due　to　their　collision　during　the　earthquake.　DAF,　however,　hasn＇t　been　introduced　in　current　Chinese　seismic　code.　In　this　work,　17　RC　frame　buildings　are　designed　with　different　fortification　intensities　and　with　different　floors　according　to　current　Chinese　seismic　Codes.　These　structures　are　further　modeled　and　analyzed　by　OpenSees.　By　comparison　with　the　quasi-static　test　data　and　the　shaking　table　test　data　for　RC　frame　structures,　the　OpenSees　models　are　verified　and　validated.　For　these　17　RC　frames,　structural　seismic　response　are　analyzed　by　nonlinear　static　procedures　(NSP)　and　nonlinear　dynamic　procedures　(NDP),　respectively,　and　the　“capacity”　values　of　structural　displacement　amplification　factors　as　well　as　their　variations　are　achieved.　It　is　shown　that　by　using　“capacity”　values　of　structural　displacement　amplification　factor,　structural　inelastic　deformations　at　collapse　limit　state　may　be　estimated.　For　RC　frames　designed　with　seismic　fortification　intensity　VI,　VII,　VIII,　the　minimum　“capacity”　value　of　structural　displacement　amplification　factor　is　15,　10　and　5,　respectively,　and　the　deformation　ability　of　designed　RC　frame　is　good.　The　ratios　between　displacement　amplification　factors　and　response　modification　factors　(i.e.　Cd/R)range　from　0.8　to　1.2,　which　are　only　slightly　larger　than　the　value　recommended　in　NEHR　Pprovisions.
