Abstract

The new east span of the San Francisco-Oakland Bay Bridge is under construction now. It is the most expensive public works project in California’s history. The bridge is designed to provide a high level of seismic performance. Even after a major earthquake, the bridge is intended to provide full service almost immediately and should sustain only repairable damage to structure. During the construction, a total of 199 strong-motion sensors will be installed at key structural members along the bridge. This paper presents various structural systems used along the bridge and discusses the instrumentation plans.
