Suspension Cable Design of the New San Francisco-Oakland Bay Bridge

摘要

Various factors contribute to the difficulty in designing the main suspension cable for the new San Francisco-Oakland Bay Bridge Self-Anchored Suspension Span (or East Bay Bridge Suspension Span). The key factors are bridge design life, cable geometry, cable anchorage layout, cable construction method, and cable corrosion protection system. This paper describes the unique main suspension cable geometry layout for the East Bay Bridge Suspension Span, reviews the available technologies for each of the aforementioned design considerations, and presents the final cable design recommendations.
