Abstract

Elastic site response analysis in cross-anisotropic deposits has been elaborated due to incidence of inclined SH wave front. A site consisting of a single cross-anisotropic soil layer rested on a half-space representing the bedrock is examined, subjected to inclined SH wave and the out-of-plane displacement amplitude is obtained by assembling the dynamic stiffness matrices of the layer and the underlying bedrock. The effects of the cross-anisotropy substantiated in form of different horizontal and vertical shear moduli were investigated and discussed accordingly. Results showed that anisotropy has great effect on the site response; however, this effect becomes immaterial when the incidence angles are almost sub-horizontal.
