Abstract: Iran with a special structure of earthquake has high seismic activity and high seismicity in the regions of high-risk earthquakes in the world. The occurrence of destructive earthquakes in the past has shown that most of the buildings are not resistant to earthquakes. Placing a large number of Iranian cities, including Tehran and Tabriz, in the near vicinity The faults increase the damage caused by the earthquake. The near-fault field earthquakes due to their specific characteristics, which distinguish them from districts of the distant sphere, have been considered seriously in recent years. Usually, in the near-shaft seismines, the vertical component may be a horizontal component B The other feature of the earthquake near the fault is that these types of earthquakes have pulse nature. Since the period of these pulses is large, most structures behave similarly to the behavior in the constant acceleration region in the response area because they move as A pulse of attenuation, such as the record of earthquakes, will not be effective.
