Juang et al (2013) combined the deterministic model by Robertson & Wride (1998) for liquefactuon potential evaluation (in terms of nominal safety factor) and the probabilistic model by Ku et al (2012) for liquefaction probability. Together, these models provide a site-specific probabilistic liquefaction-induced settlement exceedance curve (right-hand plot) and a probability density curve (left-hand plot) for the predicted settlement. The method provides a conditional probability for a given (user input design values) ground shaking level represented by a pair of amax and Mw values, along with the various design assumptions. The procedure consists of two models (based on case histories): Model A is applicable to the free-field conditions, and Model B is more applicable for estimation of liquefaction-induced building settlement. Model choice is made by selecting the appropriate box below the right-hand plot, the default is Model A - Free-field settlements. The scale for the Limiting Settlement is adjusted by modifying the "Maximum settle" value in the box below the plots.
