Abstract：Thestructureof prefabricatedconcrete buildings iscomplex，and when designingthestabilitymodelof beamcolumn wallconnectionnodes，thebondslipbetweestelandconcretewasnotconsidered，resultinginpoorsimulationperforanceof themodel.Forthispupose，stabilityanalysisofprefabricatedconcretebamcouwallconectionnodesiscariedoutbasedon BIM models.Split prefabricatedbuilding components，establisha BIM modelcomponentlibrary，andcalculate thebending capacityand shearparametersofvarious components.Basedontheusageof boltson theconection nodes of beams，columns， andwalls，calculatetherelevantparameterssuchasthebearingcapacityof teconnectionnodes.Combining BIMtechnology with Revit software，inputing component parametersandconnection node parameters from the component library，obtaining various componentmodelsandassembling themintoanoverallBIMmodel，analyzingthestabilityofconcretebeamcolumnwallcoection nodesinprefabricatedbuildings．Theresultsshowthatthemodelestablishedinthisarticlehasgoodperformance，withasimulation error of less than 1% for the stability of concrete beam column wall connection nodes.Considering the bond slip between steel and concrete，the stabilityperformanceof thesimulatednodesunderultimate load has been improved，thereby enhancing stability.
