Abstract：To evaluate thechanges inseismic performanceofbuilding structures under soil-structure interaction，anumerical calculation model wasestablishedusing the finiteelement method，takingaspecific enginering projectasanexample.A seismic simulation shaking table wasconstructedtosimulateandanalyzekeyresponseindicatorssuchasthe interlayer displacementangle，horizontal structural forces，andmaximumshearforcebornebythefoundationofthebuilding structure underseismicexcitation.Theresultsindicatethatundersoil-structure interaction，assoil stifness increases，theinterlayer displacementangleof thebuildingstructuredecreasesfromthesttothe5thfloor.Additionaly，withtheincreaseinfoundation bearing capacity，thehorizontal displacementof thebuilding structureexhibitsadownwardtrendunderlow-frequency，midfrequency，and high-frequencyseismicwaves.Undertheconditionsof transverse waves，longitudinal waves，andsurface waves，the maximum shear forceatthe baseofthe building structure first increases and thendecreases as the seismic wave velocityincreases.Theresearch findings provideanimportantbasisforoptimizingtheseismicdesignofbuilding structuresand enhancing their overall performance under soil- structure interaction.
