000011979 520__ $$2eng$$aAccording to the recent earthquakes (Northridge1994, Kobe1995, ChiChi1999, Bam2003) Near-fault Earthquake (N.F.E.) in the vicinity of quake field caused many damages which this matter motivated the researchers to examine more the Near-Source phenomenon of earthquakes. N.F.E come in large varieties rather than ordinary earthquakes and in comparison with ordinary motions they impose high seismic demand on the structure. Since IRAN is located at a zone which has a prone to having earthquakes and nearly in the majority of the country quake risk exists, and because in IRAN 2800 code of designing buildings against earthquake there is no mention of designing buildings at Near-Source zones, we conduct a research by selecting 5, 8 & 12 stories steel buildings designed according to IRAN 2800 code, to examine the effects of N.F.E. This article expresses the effects of N.F.E on frames responses by comparing the linear and nonlinear time history responses of structures to the earth motions at Far & Near-Source zones. According to nonlinear analysis the amounts of imposed demand of N.F.E were more than Far-fault Earthquake Due to inefficiency of 5, 8 & 12 stories structures according to several N.F.E, especial considerations for designing & strengthening of structures located at Near-Source zones of IRAN are required. Examining the structures’ responses shows that in Near-Source zone, structures’ seismic demand is more than Far-Source zone.
