Abstract：Inorder to studytheinfluenceof soil-structure interaction（SSIefect）ontheseismicresponseof steel-concrete windturbinetower，thefiniteelementmodelof‘tower-foundation-soil’wasestablishedbynumericalsimulationmethod，andthe nonlinear P-Υ spring was used to simulate the mutual contact between pile and soil to consider the SSI efect.Select7 nearfield pulse type long-period，far-field long-period，and nonlong-period earthquakerecords each.Basedonthe nonlinear characteristicsofsoil，consideringtheamplificationandfilteringefectsofsoilonseismicmotion，analyzetheseismicresponse of towerstructuresunderdiferent seismic motions whenconsidering the SSIefect.Research has foundthatthe SSIefect plays anadverseroleinthe seismic designof steel-concrete wind turbine towersandcannotbeignored.Undertheactionof longperiodseismic motion，thedynamicresponseinthefarfieldisgreaterthanthatinthenearfield.Afterconsideringthe SI effect，theacelerationreaches itsmaximumat theconcretecylindersectionnearthetransitionzne.Undertheactionof nonlong period，SSIefecthasagreatinfluenceontheinteralforceatthetransitionsection.Theresultsof thisstudycanprovide reference for theseismic design of steel-concrete wind turbine tower.
