Influence of Physical Modeling on Adoption of Rocking Foundations in Practice

Thumbnail_GeoCongressHistorically, structures have survived earthquakes through an inherent foundation rocking mechanism –uplift and/or sliding. Rocking structures can be self-centering and, more importantly, reduce the forces that the structure is subjected to during an earthquake. Simply put, foundation rocking is a form of base isolation that has proven to protect buildings from earthquakes. This paper, co-authored by Mark Moore, SE, quantifies and enlightens the industry on this complicated topic that is often ignored in structural analysis procedures.
