Monitoring Loading and Environmental Effects on Bridge Performance

In 2002, Wisconsin completed construction of the Land Bridge on WIS 131, the first bridge in the state to use high-performance steel, or HPS, which is lighter and easier to weld than regular steels and more resistant to fatigue, fracture, weather and corrosion. A pilot project was initiated to assess the performance of the HPS bridge members as well as to evaluate the response of the structure to actual traffic and environmental loads under in-service conditions through monitoring of strain, temperature and displacement. The two primary goals of the structural monitoring program implemented in this study were to evaluate the in-service stresses of the Land Bridge and to determine the actual load distribution caused by truck wheels on the bridge deck and tub girders.
