In this report key assumptions involved in evaluating the pile-pinning effect on bridge foundations are critiqued and a simplified probabilistic design framework is proposed for evaluating the effects of liquefaction-induced displacement on pile foundations of bridge structures. Primary sources of uncertainty are incorporated in the proposed procedure so that it is compatible with the Pacific Earthquake Engineering Research (PEER) Center performance-based earthquake engineering (PBEE) framework.
