There is evidence indicating that ground shaking near a fault rupture may be characterized by an impulsive motion that exposes structures to high input energy at the beginning of the record. This pulse-type motion is particular to the forward direction, where the fault rupture propagates toward the site at a velocity close to the shear wave velocity, causing most of the seismic energy to arrive at the site within a short time. Near-fault Earthquake (NFE) come in large variations and this variety complicates evaluation or prediction of structural response unless they can be represented by a small number of simplified motions that can reasonably replicate important Near-Fault response characteristics. In this study, three pulse type models (which proposed by Makris & Agrawal previously) is used to simulate the Near-Fault records and their effect of this simulated motions on structures are compared to the actual NFE ones. For this reason, Four Near-Fault records are selected and we conduct this research by doing time history analysis & selecting 5,8 &12 stories steel buildings designed according to IRAN 2800 code. The results show that, with limitations, Near-Fault records can be represented by equivalent pulses to understand structural response but applying this result to design process is not recommended.
