I-5 Bridge Project:

This was a three-phase project conducted at Wayne State University and funded by the U.S. Geological Survey as part of the National Earthquake Hazards Reduction Program ($218,000). As the principal investigator for Phase I (1989-90), Dr. Dusseau directed two graduate research assistants on a field trip to the Pacific Northwest in the Summer of 1989 to inventory 1,000 highway, railway, and pedestrian bridges along interstate highways I-5, I-205, and I-405 in western Washington State and northwestern Oregon. Dr. Dusseau also directed the development of a comprehensive computer database to efficiently store the data gathered in the field. As the principal investigator for Phase II (1990-91), Dr. Dusseau directed two graduate research assistants in field ambient vibration measurements and laboratory data analyses of 54 typical highway bridge spans to determine the fundamental natural frequencies of these spans. As co-principal investigator for Phase III (1991-92), Dr. Dusseau directed one graduate research assistant in the development of a procedure for finite-element computer modeling and time-history seismic analysis of reinforced concrete box-girder bridges with single-column bents.

Cantilever Truss Bridge Project:

This one-year project was conducted at Wayne State University. As the principal investigator (1986-87), Dr. Dusseau derived special non-prismatic beam finite elements to more-efficiently model cantilever truss bridges. These new finite elements were tested using the truss designs of four existing cantilever truss bridges: the Cooper River Bridge in Charleston, South Carolina; the Columbia River Bridge in Astoria, Oregon; the Carquinez Strait Bridge in Vallejo, California; and the San Francisco-Oakland Bay Bridge in Oakland, California.
