ABSTRACT

In this study we used a simplified foundation model based on the upper-bound plasticity theory (Murff & Wesselink 1986, Murff 1987, Tang & Gilbert 1992, Murff 1999, and OTRC 2009) to analyze various structural factors affecting foundation system capacity. We

also used a three-dimensional (3-D) structural model, SACS™, based on the finite element method to perform pushover analysis to estimate the capacity of the structural system including the foundation. The 3-D model was also used to infer the hurricane load on the foundation from the hindcast wave, wind and current conditions in the hurricane.
