In this research the seismic demand of RCS structures under the near-fault earthquakes is investigated. For this purpose 5 RCS intermediate moment frames with 4, 7, 10, 15 and 20 stories and 5 spans (span length 5 and 7m) were designed. Then nonlinear dynamic analysis was performed on the structures using the OpenSees software. Results show that the stories displacement under the near-fault earthquakes is larger than the far-fault earthquakes so that with increase in the structure height the difference between them decreases. In high rise structure with 7m length span, the drift-angle due to the far-fault earthquake is greater than the near-fault earthquake.
