Abstract
The objective of this paper is to make a clear the influences of the analytical dimension for modeling the spatial distribution due to the inhomogenity of soil properties on the strong nonlinear seismic response. 2D and 1D FE models are used to consider either the vertical and horizontal distribution of the soil property or the vertical distribution of the soil property. The hyperbolic model is used as a nonlinear model of the soil property. The shear wave velocity and the internal friction angle in the model are taken into account of the variables with the spatial distribution. The spatial distribution is generated by using a sample function of a discretized Gausian stochastic field and is considered the characteristics values to be realistic. It is found that the earthquake responses of the two dimensional model behavior like one dimension. The issue is obtained that the information with the spatial distribution is not sufficient.
