STRONG-MOTION INSTRUMENTATION PROGRAM FOR STATE HIGHWAY BRIDGES

The State Bridge Seismic Network, supported by the Federal Highway Administration, was established in spring 1974 to instrument highway bridges in seismically active regions. This network is being integrated into the existing National Strong-Motion Instrumentation Network operated by the U.S. Geological Survey. Six bridges in California, Alaska, and Nevada have been instrumented. The most recently installed instrumentation uses a central recording system that permits greater flexibility in locating transducers. For bridge structures with numerous expansion joints, adjacent sections are instrumented so that relative motion across the joints can be interpreted. The response during the 1971 San Fernando earthquake of a seven-story, reinforced concrete building supported by a moment-resistant frame is used to illustrate a simplified interpretation of results from such systems. Instrumentation of representative types of structures will lead to improved modeling and analysis of the response of bridge structures to earthquakes.
