This paper presents a study to evaluate the soil effects on earthquake ground motion of two selected sites in the Memphis area. Twenty artificial bedrock acceleration time histories with characteristics representing potential earthquakes in the Memphis area are generated. The effect of bedrock locations on the soil amplification is also evaluated. The results of both sites show that the peak ground acceleration is amplified about 1.5 times and the dominant frequency of shaking is shifted significantly. This finding is of great value for design of structures.
