Research Impact

This work has the potential to alter the manner in which liquefaction manifestations are evaluated for bridges, buildings, and other infrastructure projects. Existing fines corrections simultaneously account for the influence of fines on penetration resistance, and on liquefaction resistance. Separating these two effects will clarify fundamental mechanisms and potentially reduce uncertainty in our predictions. Utilizing alternative intensity measures has the potential to decrease uncertainty in liquefaction evaluations, and also simplify the demands from a vector of PGA and M to a single constant associated with an evolutionary intensity measure.
