Title:SeismicAnalysisofRCFrameStructuresusingSubfactorCoefficientsandInverseAnalysisforCollapsePrediction
Abstract:

Introduction:
Reinforcedconcrete(RC)framestructuresarewidelyusedintheconstructionindustryduetotheirstrength,durability,andcost-effectiveness.However,theunpredictabilityofearthquakesposesasignificantchallengeinassessingtheirseismicperformance.SeveralstudieshavebeenconductedtodevelopmethodsforanalyzingandpredictingthecollapsepotentialofRCframestructures.ThispaperexplorestheuseofsubfactorcoefficientsandinverseanalysisasinnovativeapproachesintheseismicanalysisofRCframestructures.
