Abstract
Based on numerical simulation and the statistics of fine sand layers in the Wuhan area (China), the effects of uncertainty of dynamic shear modulus (due to the limited range of current instruments) ratio on design ground motion were explored. Its effects on design seismic acceleration response spectrum, platform value of response spectrum, and characteristic period of response spectrum were analyzed quantitatively. This study could provide a guideline for the analysis of seismic response as well as theoretical study of nonlinear dynamics on geotechnical earthquake engineering.
