WAVE INTERPRETATION OF STRONG EARTHQUAKE GROUND MOTIONS
|
抄録（英）：
A multiple filter technique is applied to strong earthquake ground motions in order to get nonstationary spectral characteristics. The analysis of several typical SMAC records obtained in Japan indicates that a significant portion of strong earthquake ground motion has a kind of regularity in nonstationary spectral characteristics. The regularity is explained by dispersion characteristics of surface waves. A simulation computation for surface waves propagating through a heterogeneous ground is carried out to verify the adequacy of the explanation. It is concluded that the principal motions of the SMAC records consist of surface waves.
