Seismic Retrofit of a Historic Pier on Soft Soil
Puget Sound Naval Shipyard’s Pier 3, constructed between 1941 and 1942, is located in Bremerton, Washington. It was constructed similarly to bridges of that period, using large- diameter columns and massive footings. Due to the era of construction, ductile detailing was not provided at important connections within the lateral load path. In addition, the massive footings supported on timber piles and surrounded by soft clay are relatively flexible in the lateral direction. The combination of these factors has made seismic performance a primary concern for the pier, which, despite being nearly 80 years old, is in good condition. Consequently, the owner commissioned a study to investigate the feasibility of seismically retrofitting the pier to extend its useful life. This paper describes the detailed analysis that was performed to confirm the feasibility of retrofitting Pier 3 with lead-rubber bearings and provides an example of the potential cost savings from implementing such a retrofit.
