Abstract
In geotechnical earthquake engineering seismic site response analysis is a very complex
task, which has gained an increasing importance for the last decades. This paper aims
to numerically simulate the effect of an earthquake input in different types of soil layers
in order to get the dynamic amplification factor. The methodology for correctly
simulation of seismic waves propagation includes thorough theoretical background
aided with different softwares (Shake, Strata,DeepSoil and Plaxis) which allow the
simulation of soil as nonlinear material model or small strain linearly elastic material.
The verification of the model is done by comparison of numerical results in relation to
two different soil profiles from Varazdin, Croatia and from Skopje, Macedonia. The
proposed approach should demonstrate and illustrate the special points in taking into
account the modelling of different layers. The earthquake input is given as acceleration
signal which in case of low densities of soil material are prone to initiate higher
amplifications. Finally, the advantages and limitations of the proposed numerical model
are discussed in detail.
