Seismic motion amplification ratio corresponding to fundamental period, Gs₁, is a very important factor used for evaluating site effects. In this paper, a simple procedure for evaluating Gs₁ of layered soil profiles is proposed. Firstly, a theoretical formula for Gs₁ of a two-layer soil profile on elastic bedrock, is developed. For a multi-layer soil profile, the multiple soil layers are approximately replaced by equivalent two layers, then Gs₁ of the multi-layer soil profile can be estimated by that of the equivalent two-layer soil profile on bedrock. To demonstrate the validity of this development, Gs₁ of 68 representative soil profiles are evaluated, it is shown that the results by the proposed procedure agree well with those by the wave propagation method. Moreover, applying the proposed method for Gs₁, free field response spectrum of 4 soil profiles are evaluated, and compared with the results by program SHAKE, good agreement between results by the two methods is observed.
