Fatigue assessment for deck plates in orthotropic bridge decks

Fatigue assessment for deck plates in orthotropic bridge decks Since the 1960s, orthotropic deck plates of highway bridges have been built with large cold‐formed trapezoidal stiffeners supporting a deck plate with a thickness of approx. 12 mm. The maximum cross‐beam spacing is approx. 4 m. A number of these bridge decks in The Netherlands suffer from fatigue cracks in the deck plate. First cracks have been observed after about 30 years in service. In one particular movable bridge, the cracks were found after only seven years. In many other countries, this type of crack has not yet been observed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Steel Construction: Design and Research Wiley

Abstract

Since the 1960s, orthotropic deck plates of highway bridges have been built with large cold‐formed trapezoidal stiffeners supporting a deck plate with a thickness of approx. 12 mm. The maximum cross‐beam spacing is approx. 4 m. A number of these bridge decks in The Netherlands suffer from fatigue cracks in the deck plate. First cracks have been observed after about 30 years in service. In one particular movable bridge, the cracks were found after only seven years. In many other countries, this type of crack has not yet been observed.
