CENTRAL UNITED STATES BRIDGE RESEARCH:

I-55 Bridge Database Project:

This was a one-year project that was conducted at Rowan University and that was funded by the U.S. Geological Survey as part of the National Earthquake Hazards Reduction Program ($42,342). As the principal investigator for this project (1997-98) at Rowan University, Dr. Dusseau directed two undergraduate research assistants in the development of a comprehensive computer database for all interstate highway bridges in southeastern Missouri and northeastern Arkansas. This database currently contains information on 271 bridges including over 1500 records and 175 fields of information.

I-55 Bridge Vibration Project:

This was a one-year project that was conducted at Wayne State University and that was funded by the U.S. Geological Survey as part of the National Earthquake Hazards Reduction Program ($53,900). As the principal investigator for this project (1994-95), Dr. Dusseau directed two graduate student assistants in field ambient vibration analyses of 25 typical highway bridge spans along interstate highways I-55, I-57, and I-155 between St. Louis, Missouri and the Missouri-Arkansas State Line. The goal of these field measurements was to determine the fundamental natural frequencies for each bridge span. These field-measured frequencies were used to develop empirical formulas for estimating the fundamental natural frequencies of the other highway bridges along I-55, I-57, and I-155. Dr. Dusseau and his students also developed a computer database for all highway bridges along I-55, I-57, and I-155 in southeastern Missouri. This I-55 Bridge Database was used in conjunction with the empirical formulas to extrapolate the field-measured frequencies for the 25 typical highway bridge spans to all of the highway bridges in the database.
