To　study　the　influence　of　hysteretic　behavior　of　material　on　the　seismic　collapse-resistant　capacity　of　reinforced　concrete　frame　structure,　a　5-story　plane　frame　was　selected　as　the　research　object,　the　incremental　dynamic　analysis　method　was　used　to　analyze　the　collapse　vulnerability　of　the　structure.　According　to　the　collapse　probability　curve,　the　seismic　collapse-resistant　capacity　of　the　RC　frame　structure　with　different　hysteresis　parameters　was　quantitatively　evaluated.　The　research　shows　that　the　concrete　strength　grade　has　the　most　significant　influence　on　the　seismic　collapse-　resistant　capacity.　Reducing　the　concrete　strength　degradation　or　increasing　the　strain　hardening　rate　of　the　steel　can　slightly　improve　the　seismic　collapse-resistant　capacity　ability;　The　concrete　hysteresis　pinch　and　the　steel　hysteresis　energy　consumption　has　no　effect　on　the　seismic　collapse-resistant　capacity　of　the　structure.　The　seismic　collapse-resistant　capacity　of　the　structure　is　negatively　correlated　with　the　strength　grade　of　the　steel　bar,　but　its　impact　is　not　obvious.　©　Published　under　licence　by　IOP　Publishing　Ltd.
