Abstract:
Regarding the catastrophic aftermath of earthquakes, having a reliable approach to assess the seismic demands proper to the region of interest seems inevitable. The scope of this study is to provide a list of far-field seismic records applicable to 2-D nonlinear time history analyses in Iran. To do that a set of 2222seismic records from Iran's seismic records database has been investigated based-on their characteristics, amongst are focal distance, magnitude, rupture mechanism, frequency content, and soil profile.For the purpose of this study, at first, all the 2222 records have been categorized based on their focal distance and the records with Peak Ground Acceleration less than 2.1 on scale of g, and records with focal distance less than 5km have been omitted. In the second step, the remaining records have been set into categories based on their stations' soil profile. For the next step, the database from previous step is organized according to their rupture mechanism, and in last step, the records with the characteristics of near-fault ground motions are excluded. Finally an ensemble of 22 seismic records is selected from the aforementioned set that is suited for 2-D nonlinear time history analyses in Iran
