The main goal of this study was to develop a simple practical tool to estimate soil dynamic amplification factors to be used for earthquake design of structures with different natural periods in the region. Totally, 75 geotechnical profiles in the region were collected from different private and governmental sources. Earthquake response analyses of these profiles were conducted by SHAKE91 using 18 worldwide strong ground motions. For each profile 18 amplification spectra were calculated. The amplification spectra of all profiles were then averaged and mean amplification spectrum of the site was derived. The amplification spectrum of the site was smoothed and a simple practical amplification spectrum was recommended for southwest of Tehran. In order to obtain design spectrum of the site, acceleration response spectra of all records were averaged, multiplied to the recommended amplification response spectrum, and smoothed. The design spectrum of the site was compared with standard design spectrum of Iranian Building Code and modification remarks were suggested.
