SEISMIC SAFETY OF STRUCTURESCASE STUDY:PROBABILISTIC METHODOLOGICAL APPROACHTO DEFINITION OF SEISMIC INPUT

摘要

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