Abstract
Earthquake damage Civil engineering structure and bridges are no exception. Historically, bridges have proven to be vulnerable to earthquakes which cause damage to substructures and foundations and in some cases being totally destroyed as Superstructure collapse from their supporting elements. The bridges in New York City are required to comply with Specifications of American Association of State Highway and Transportation Officials (AASHTO) and New York State Department of Transportation (NYSDOT). The seismic design criteria has been recently introduced in these specifications and all bridge projects in New York City must comply with these requirements. The extent of seismic analysis required varies with bridge's scope of rehabilitation or replacement scheme. The New York City Metropolitan area presents foundation engineers with a wide variety of soil profiles that varies from soft clay to compact glacial deposits. Local bedrock configurations are similarly extremely variable. The thickness and quality of the soil overburden generally plays a significant role in the seismic design of bridges. The paper summarizes the available geotechnical information regarding seismic design of bridges in New York City and discusses the geology, seismicity, seismic risk, various subsurface soils encountered in the area and their liquefaction potential. Seismic evaluation being performed on several of its important bridges is briefly presented.
