Probabilistic liquefaction risk analysis including fuzzy variables

Abstract A new method of probabilistic liquefaction risk analysis is developed. The variables whose effect on the process of liquefaction are known vaguely and described only through imprecise linguistic terms, are treated as fuzzy variables. The combined effect of the fuzzy variables is introduced into a basic model of transformed into a random variable. The probability of liquefaction is then formulated in the usual framework of probabilistic risk analysis. Illustrative example analyses are also presented.
