Abstract

A methodological approach to definition of seismic input for seismic safety analyses of structures is presented in this paper. Recorded accelerogrammes of occurred strong earthquakes have been used as seismic input, while their participation in the seismic safety of structures has been defined based on the seismic activity of the seismic sources around the considered site. The developed methodological approach is probabilistic and it includes treatment of uncertainties of the used attenuation laws. Four probabilistic distributions (normal, limited normal, triangular and beta) have been used for treatment of the uncertainties. The methodological approach has been verified by consideration of a hypothetical location in Republic of Macedonia.
