Paper Title:
The Effect of Nonlinear Dynamic Shear Modulus under Anisotropic Consolidation on Response Spectrum of Soil Layer
  Abstract

The dynamic shear modulus (DSM) is the most basic soil parameter in earthquake or other dynamic loading conditions and can be obtained through testing in the field and in the laboratory. By using the resonant column tests, the effect of the consolidation ratios on the nonlinear behavior of DSM versus the shear strain, G/Gmax-γ, for two types of sands and fourteen types of undisturbed silty soil is investigated and its effect on the surface response spectrum is presented in the paper. The results here indicate that consolidation ratios have certain effect on the shape of the nonlinear behavior of DSM versus the shear strain and G/Gmax increases with increasing of the consolidation ratios. By comparing to the isotropic consolidation, the consideration for the actual anisotropic consolidation makes the acceleration peak amplitude increase and makes the characteristic period decrease. For the incidence of the strong seismic excitation, the effect of the anisotropic consolidation on earthquake ground motion should be considered.
