What is Evaluation des differents parametres utilises pour l'estimation du contenu en frequences des mouvements du sol, avec application aux forts tremblements de terre de Vrancea, Roumanie about?

The paper presents results of a comprehensive study of ground motions recorded during the strong earthquakes (moment magnitude Mw > 6) generated during last 34 years by the seismic source of Vrancea, Romania. By analyzing over 300 accelerograms, the capacity of different expressions in the literature to estimate the predominant period of a ground motion is compared. The correlation between the values obtained from different evaluations is assessed as well. The dependence of the predominant period of different factors of influence is analysed. Comparisons are made between the parameters determined for the same seismic event at different stations, as well as for ground motions recorded on the same site at successive earthquakes. The results are interpreted in correlation with the information provided by frequency bandwidth parameters. Considerations are made on the measure in which the influence on the frequency content of the source and of local geological conditions can be separated, for seismic motions recorded on different locations.
