摘要

Dynamic analysis to obtain the seismic indeuced deformation on the sturucture is a key issue in performance-based design. The appropriateness of the results from dynamic analysis depends on the appropriateness of the input parameters. In this study, an index to represent the degree of the parameter appropriateness is discussed. Indexes of the similarity in the liquefaction resistance curves both from tests and numerical simulations are proposed. Then, the relationship between the differences in the FEM analysis results with various parameters and the indexes of these various input parameters are examined. The proposed indexes are expected as a reference in the parameter determination in effective stress analysis.
