Abstract

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