Local soil response to seismic input compatible with uniform hazard spectra at bedrock

  • G. S. StamatovskaEmail author


The paper presents the results from the investigations of the effect of the local soil characteristics upon the seismic response at the surface of the Skopje city region. The SHAKE2000 computer program was used. Four soil profiles with a total thickness ranging between 7 m and 30 m were considered. The soil dynamic properties were defined by using data on the Skopje city region reported in literature. Horizontally, the soil layers were modeled as a one-dimensional soil column subjected to horizontal earthquake motion at the base. The seismic motions were defined using sets of four synthetic accelerograms compatible with the uniform hazard spectra at bedrock for return periods of 95, 475 and 1000 years. The results represent transfer functions as a representative measure of amplitude-frequency modification of local soils and absolute acceleration response spectrum at the free surface. The amplification factor was computed as a ratio between the acceleration spectra at the free surface and those at bedrock.
