Seismic Assessment and Retrofit of Existing Multi-Column Bent Bridges

The bridge seismic retrofit program has essentially completed retrofitting all of the single column bridges. The next category of bridges, those with multiply columns in each bent, raise questions as to what the correct and most economical approach should be to retrofitting. Research will focus on assessing the seismic vulnerability of typical multi-column bent bridges and providing retrofit strategies that do not require the treatment of every column in every bent. Retrofitting every column would be both time and cost prohibitive. Primary benefit would be cost savings.
