Abstract
Inelastic behavior of large diameter extended pile shafts subjected to earthquake shaking and liquefaction-induced lateral spreading is investigated. A series of Nonlinear Dynamic Finite Element Analyses (NDA) are performed covering a range of soil, pile, and ground motion conditions. Results showed that combined effects of lateral spreading and inertia produce larger demands that cannot always be enveloped by designing the pile for each load case separately. The NDA results were used to develop an Equivalent Static Analysis (ESA) method.
