An earthquake-resistant design should include the effect of local site conditions on the seismic ground motions. In this study, ground response analyses in 22 locations around the developing town of SaruhanlA +/- in the Aegean Region of Turkey were undertaken using SHAKE software. The ground response analyses for a typical soil profile considered various modulus reduction and damping curves including effective confining stress and a plasticity index dependent model. The confining stress-dependent soil models and shear-wave velocity profile resulted in higher amplification ratios and lower predominant periods. High acceleration ratios (> 3) and lower predominant site periods were found in the eastern part of the site such that buildings of ten or more storeys would be severely damaged.
