Effects of Heavy-Axle-Loads on the Steel Bridge at FAST

Ongoing studies of a two-span bridge in Pueblo, Colorado, are providing information to test the performance of various repair techniques in order to extend the life of existing railroad bridges. Results of the tests on the 101-year old 55.5-foot riveted girder span are typical of an older span with years of corrosion while the 56-year old 65-foot welded girder span are typical of more recent construction. The 65-foot welded girder span developed two significant cracks and data recorded just before the second crack indicated that the corrugated rail resulted in increased dynamic loading. Past studies have indicated that corrugated rail can also produce high dynamic loads that result in increased fatigue damage and that a smooth rail surface free of discontinuities can minimize dynamic loading on the structure.
