000011694 520__ $$2eng$$aThe duration of strong shaking is one of the key parameters in engineering analysis and earthquake resistant design of structures, since the damaging effects of an earthquake as well as operational reliability of equipment are often related to the duration of strong shaking. There are several definitions of duration, as described in the paper. In this study, the so-called relative significant duration has mainly been applied. A model is presented for the relative significant duration using regression analysis based on an appropriate data set for moment magnitude and source-to-site distance. The data set applied is taken from the ISESD databank and contains shallow strike-slip earthquakes from Armenia, Greece, Iceland, Italy, Slovenia and Turkey. Main emphasis is placed on rock site conditions. The relative significant duration appears to represent the S-phase of ground shaking in the near and intermediate fault area reasonably well, but for the cases studied the S-waves create the dominating horizontal seismic action on structures. However it is also seen that the uncertainties reflected by the residual error can be significant.
