摘要

The seismically vulnerable East Span of the San Francisco-Oakland Bay Bridge will be replaced with a dual east bound and west bound 3.6 km long parallel structure. The cost of the replacement bridge is estimated at $1.5 billion and the bridge will be constructed by the year 2004. The Bay Bridge lies between the HaYward and the San Andreas faults which can generate magnitude 7.5 M and 8.1 M earthquakes, respectively. Performance criteria require that the bridge must be operational immediately following a 1500-year return period earthquake from either of these two faults. Four distinct structures will make up the bridge crossing: a low rise post-tensioned concrete box girder near the Oakland shore; a 2.4 km long segmental concrete box girder; a self-anchored suspension signature span; and a post-tensioned concrete box girder that connects to the east portal of the Yerba Buena Island tunnel. This paper is part of a trilogy of papers presented on the design of the new San Francisco-Oakland Bay Bridge. This first paper focuses on the design parameters and constraints, design evolution, bridge type selection process, selected design's major structural and architectural characteristics and structural details. The second and third papers focus on the design of the substructure and superstructure of the new San Francisco-Oakland Bay Bridge Self-Anchored Suspension Span, respectively.
