Finn's method (1985)

For the computation of the Cyclic Resistance Ratio CRR, Finn proposed a relationship in which the independent variables are the magnitude M and the corrected number of blows from the standard penetration test SPT





Fs is obtained from:


CSR is calculated using the expression developed by Seed and Idriss (1971-1982) where the reduction factor rd is determined using the empirical formula proposed by Iwasaki et al. (1978)
