Modeling Uplift and Collapse of Structures during Earthquakes: Centrifuge Modeling and Rocking Dynamics
Matthew DeJong, Assistant Professor, Department of Civil and Environmental Engineering, University of California, Berkeley,

This presentation will focus on large displacement dynamic effects of structural uplift, or rocking, during earthquakes. The following will be considered: 1) structures that naturally rotate and uplift on their foundations, 2) structures that are designed to rock above their foundation, and 3) structural elements that may rock and overturn. Results from a series of centrifuge tests involving soil-structure interaction of uplifting structures will be compared with computational modeling results. A new computational modeling tool designed to capture dynamic amplification, as well as local rocking collapse, will also be described and applied to case study structures.
