Comparison among Iran, Turkey and Kobe Earthquakes from the View Point of Ground Motion Characteristics and Damage

Abstract

Comparison among major earthquakes occurred in Turkey (1999), Kobe (1995) and Iran (Manjil, 1990 and Tabas, 1978) from the view point of Ground Motion Parameters (GMP) and building damages is investigated in this study. Peak Ground Acceleration (PGA), Velocity (PGV) and Displacement (PGD) as well as Spectral Intensity (SI), Power Spectral Intensity (PSI) and finally, Predominant Frequency (PF) are considered as GMP. Totally, 30 acceleration-time histories of the earthquakes having PGA more than 100 gal were dealt with. GMP of 4 records of each earthquake having big PGA are compared with each other and outline of damage in each earthquake is given.
