- Abstract:
- According to the Toro share velocity model,we use the Monte Carlo method to generate 200 shear velocities,thickness and density random samples for uncertainty analysis,based on soil structure from the Turkey Flat site.Computing the quarter-wavelength(QWL)method amplification factor as well as transfer function(TF)and estimating their sensitivity under four conditions made up of random soil samples mentioned above.The results show that uncertainties of shear velocity,thickness and density have same impact on the spectrum characteristics using two methods.The influence of shear velocity on both amplification factors and fundamental frequency is predominant among different soil parameters.In addition,amplification factors and fundamental frequency of QWL are less sensitive to random soil parameters than that of TF's.
