The　law　of　the　progressive-collapse(PC)resistance　capacity　of　the　typical　reinforced　concrete(RC)frames　is　studied　to　provide　a　reference　for　PC　design　and　research.　The　PC　resistance　capacities　of　the　typical　non-integrated　slab　and　the　integrated　cast-in-situ　slab　RC　frames,　with　different　seismic　fortification　levels,　are　compared　based　on　the　nonlinear　static　Pushdown　method.　It　is　found　that　the　uncoordinated　development　of　internal　forces　of　beams　on　different　stories　leads　to　the　lower　PC　resistance　capacity　for　the　frame　when　multi-storey　frame　beams　commonly　resist　PC.　The　PC　resistance　capacity　of　the　frame　under　the　beam　action　and　catenary　action　is　dominated　by　the　flexural　capacity　and　tensile　capacity　of　frame　beams　respectively.　After　anti-seismic　design,　the　PC　resistance　capacity　of　the　frame　under　the　beam　action　is　significantly　enhanced,　but　the　capacity　under　the　catenary　action　is　improved　slightly.　The　PC　resistance　capacity　of　the　frame　under　the　beam　action　is　significantly　enhanced　by　integrated　slab;　however,　for　the　capacity　under　the　catenary　action,　the　enhancement　extent　relates　to　the　width　of　slabs.
