Popis: A computation of 1D and 3D seismic motion parameters was made and the influence of input parameters on these parameters were analysed. A modelling was realised on the examples of sedimentary structures geotechnical models. This comparison provides different spectral and frequencial values and spectral accelerations. The differences in seismic response spectra are influenced not only by properties of geological structures but also by the methodics of the soil structure interaction modeling and input time history spectral composition. However, the influence of geotechnical properties of geological structures on the output results are apparent. The modelling results of different input time history spectral composition, the Ricker impuls and the Gabor function were compared. In the area of cement factory in Rohožník, the new rotary kiln furnance is planned to be build. In the sense of STN 73 0036 the expert seismic judgment has been claimed. The standard and local seismic response spectra is computed for the place where the rotary kiln will be situated. The application of the local spectral acceleration in seismic load computations enables to save costs in comparing with the standard acceleration.
