Abstract
The design for a major cable-stayed bridge under construction in seismically-active Charleston, South Carolina, included rock islands around the main span piers as protection from ship impact. Considering the historical seismic activity of the region, a primary concern was the potential for instability of the rock island slopes during a major earthquake. This paper compares results from modeling of the rock island and ship channel using the dynamic two-dimensional finite difference software FLAC to the results from conventional pseudo-static analysis.
