The tower is situated in north-west of Tehran, few kilometers from the known “North Tehran” and “Ray” active faults. Therefore, taking into account the near field aspects of strong motion in the design of such an important structure is necessary. In present study, time histories at the tower’s site, for different scenario earthquakes along the nearest sources are simulated using the stochastic finite-fault simulation method of Beresnev and Atkinson (1997, 1998). The stick model for the tower is constructed and the effects of different fault rupture scenario on the response of the structure under simulated earthquake excitations are investigated. We have explored the sensitivity of the results to the variation of the nucleation point, so, all other parameters such as the stress drop and strength radiation factor are assumed at their best estimate values. For each fault model, three different nucleation points is considered and the resultant motions are generate using a random slip distribution on the fault plane. The results show that changing the nucleation point results in the variation of the response of the tower more than hundred percent in some cases. The computed acceleration time histories and response spectra would be the most useful tools for design engineers and the results of the seismic response analyses enables designer to have a better insight into the overall response of the tower during the most expected seismic motions.
