Abstract: “This work is conducted to investigate the effects of near fault ground motions on the peak story drift ratios and structural elements’ displacements. Two sets, each consists of seven near fault ground motion records are prepared. The records of each set are scaled in order that their average spectrum approaches to the design response spectrum by following the rules provided in ASCE/SEI 07-10. One of the sets consists of records with pulses whereas the other is established with records without pulses. A ten story steel special moment frame is designed to the Load and Resistance Factor Design of the ANSI/AISC 360-10. Applied capacity based design principles for providing global ductility are along with ANSI/AISC 341-10. The loads and load combinations are compatible with ASCE/SEI 7-10. The results indicate that although the peak values do not change much, the dispersion of the drift ratios and the element displacements are considerably higher for the set of pulse type records.”
