Numerical analysis of soil–structure systems at seismic fault pulses has investigated. Vibrationtransmissibility of the soil–structure interaction has analyzed for super-structures with different aspect ratios positionedon various soil types and different foundations have studied. Soil structure interaction with geometric nonlinearity hasbeen considered with forward directivity and fling step types of mathematical seismic fault pulses. It has been analyzedthat nonlinear SSI is tend to amplify the acceleration responses when subjected to low frequency incident pulses belownormalized threshold frequencies. These thresholds associate with soil classification, so that different soil type ha svarious shear wave velocity. With increased shear wave velocity of the underlying soil makes the threshold frequencyincreases.
