Abstract

Erbil city characterized by the risk of earthquakes generated by Zagros-Taurus Belt. The central objective of this study is to obtain a compatible input ground motion within the seismicity of Erbil city since which is considered an essential component of seismic risk evaluation and vulnerability studies. The real records obtained from the online database Pacific Earthquake Engineering Research Next Generation Attenuation. Four sets of ground motion selection and modification methods proposed to obtain fifteen records, where each record scaled and matched with the defined target spectra and seismic characteristics in Erbil city. Based on the greatest number of repetition and different events, ten compatible ground motions with earthquake name and NGA record number are selected: Gazli_Ussr (#126), Imperial Vally_06 (#183), El Mayor-Cucapah_Maxico (#5827), Christchurch_New Zealand (#8124), Imperial Valley (#6), Darfield_NewZealand (#6893), Duzce Turkey (#1602), Northridge_01 (#1082), Loma Prieta (#761), and Spitak_Armenia (#730). Seismosoft application utilized to obtain the graphs of acceleration, velocity, and displacement time histories for three components, in addition to determine the important parameters to characterize the amplitude, frequency content, and duration of the selected ground motion.
