Monitoring Loading and Environmental Effects on Bridge Performance, Research Brief.

摘要

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. Prior to construction of the bridge, the researchers for the current study performed laboratory tests to evaluate the fatigue resistance properties of the steel to be used. These tests are discussed in the report Fatigue Strength of Steel Beams with Hybrid HPS70W/A588W, sponsored in part by the Innovative Bridge Research and Construction Program of the Federal Highway Administration. The report is available from the WisDOT Library.
