Abstrakt: Study aims at selecting the suitable shear modulus reduction and damping curve for broad classification of soil, i.e., rock, gravel, sand, and clay. For this purpose, surface and bedrock ground motion recordings from KiK-Net downhole array for both deep and shallow soil sites have been used. Total stress one-dimensional non-linear site-response analysis has been carried out by varying the available curves for a corresponding soil type. Input parameters for few curves have been determined using parametric study. Linear mixed-effect models on residuals from predicted and recorded surface spectra have been used in suggesting the suitable curve for corresponding soil. [ABSTRACT FROM AUTHOR]
