Abstract

Time histories of strong ground motion records are of great importance in the field of structural earthquake engineering. They are used as input data in various studies aiming at earthquake protection of structures. Real, artificial, and synthetic seismograms are the three kinds of these input data. Real seismograms are those recorded during earthquake events, artificial seismograms are known as those numerically generate in such a way that their response spectrum corresponds to a target spectrum, and synthetic seismograms are those obtained based on geological considerations (Rezaeian and Kiureghian, 2010). The real seismograms are sometimes unavailable even in high seismicity regions, when strong earthquakes have not been recorded after major historical earthquakes. Such a lack can be overcome through the application of modified real ground motions from other regions, which is a controversial method and may result in unrealistic evaluations (Shahjouei and Pezeshk, 2015). Historical earthquakes should then be synthesized. This is the objective of research being presented.
