Amplitude and frequency content are two important features of the earthquake which are different for near and far-fault earthquakes and in most of the standards, effects of the near -field earthquakes in loading are not considered. So study and comparison of these effects on structures is necessary. In this paper, structures operation against near and far fault earthquakes for two near sites and two far sites have been investigated. For this purpose, in order to achieve operation point of a six stairs structural model with mean lateral bending frame resistant system, from special plan spectrums of two different sites, near and far fault, which are obtained from seismic hazard analysis is used. Evaluation of effects due to near and far fault earthquakes based on the Iran’s standard 2800 ranges on operation point and also comparison of operation effects of near and far fault spectrums with Iran’s standard are results of this research work. In continues, after presentation of obtained results from time history analyses, some suggestions have been proposed for design correction based on the regulations in near -field earthquakes.
