Abstract

Strong
ground shaking causes severe damages to man-made facilities and sometimes
induce loss of human lives. Studies of the characteristics of observed
accelerograms from earthquake events upgrade one‟s capability in seismic hazard
mitigation. The review of the seismic activity affecting the territory of
Kosovo, points out that the region should be considered as having high seismic
hazard potential. In order to be able to assess the seismic hazard, it is
necessary to integrate data from various fields such as seismology, geology,
tectonics, geophysics etc. The number of real earthquake histories registered
in the territory of Kosovo is very limited, because the first seismological
stations were installed, very recently. This is especially a problem when it
comes to dynamic structural analysis. Seismic ground motions of high-frequency
are generally required as input for non-linear dynamic structural analysis by
engineers, especially for those who are engaged in performance-based seismic
design. Simulating earthquake ground motions 
by models that correctly describe the intensity and frequency content
variation with time will allow more accurate prediction of structural
performance. The finite-fault model method was used for simulation of strong
ground motions for several locations in Kosova.
