Obciążenia sejsmiczne ze względu na swój losowy charakter stanowią jedno z większych wyzwań stawianych współczesnej inżynierii. Na obszarze Polski problem naturalnej sejsmiczności jest niewielki i dotyczy głównie obszaru wzdłuż południowej granicy. Większe zainteresowanie trzęsieniami ziemi ma związek z coraz częstszym projektowaniem obiektów zlokalizowanych w rejonach o podwyższonej aktywności sejsmicznej, poza terenami Polski. Artykuł skupia się na odpowiednim wyborze danych, służących do przeprowadzania analiz w dziedzinie czasu (time-history), które ze względu na coraz większą uwagę zwracaną na przewidywanie zachowania konstrukcji (performance based design), są powszechniej stosowane.

EN

Due to their random nature, seismical loads pose one of greater challenges to modern engineering. Within the territory of Poland, the problem of natural seismicity is little and it concerns mainly the area along the southern border. Greater interest in earthquakes stems from more and more frequent cases of designing facilities located in regions with increased seismical activity outside Poland. The article focuses on adequate selection of data which serve to perform analyses in the time-history scope, which are more commonly used due to constantly growing attention devoted to predicting the construction behaviour (performance based design).
