Fatigue of Orthotropic Steel Decks
Journal of the Structural Division, 1972Experimental investigations reported on the fatigue behavior of orthotropic steel bridge decks have been rather limited. Results of fatigue tests on steel orthotropic decks with both conventional and biserrated trapezoidal ribs are presented. In the first phase, tests on two types of deck to rib plate welded connections unflanged and flanged ribs, and ...

Renovation of Orthotropic Steel Bridge Decks
IABSE Reports, 2013<p>This paper is about the renovation of orthotropic steel deck bridges. It proposes a new solution for placing an overlay of prefabricated HSRC elements on the bridge deck to prevent fatigue damage.</p>

Monitoring fatigue effects in an orthotropic steel bridge deck
IABSE Reports, 2013<p>The effect of fatigue is particularly relevant in steel bridges since the influence of traffic load cycles on serviceability limit stress values is very high if compared to relatively low dead weights.</p><p>Orthotropic steel decks, directly subjected to traffic loads, are very sensitive to fatigue: in most cases, fatigue defects ...

Steel Orthotropic Decks: Developments in the 1990s
Transportation Research Record: Journal of the Transportation Research Board, 1999Recent developments in the field of steel orthotropic decks, which made possible the design of several recently completed highway bridges with record-breaking spans, are summarized. The more efficient, but fatigue sensitive, decks with closed ribs were prevalently used.

Cracks in Steel Orthotropic Decks
1990Many cracks have been discovered in steel orthotropic decks during the past 12 years. They occurred either at the rib-to-deck plate junction or at the rib-to-floor beam junction, depending on local facts. Frequent inspections on a large number of decks allowed observation of their appearance and progress in order to set up a plan of action and repair ...

Fatigue Assessment of Orthotropic Steel Bridge Decks
1990Fatigue failures have occurred in the steel orthotropic decks of several bridges in Europe, some after little more than a decade in service. This has led not only to expensive inspection and repair procedures but has also highlighted the difficulty of assessing these decks, which lie outside the scope of most design codes.

Assessment of fatigue cracks in orthotropic steel decks
Steel Construction, 2009AbstractThis study proposes a new “health” evaluation system for fatigue cracks in orthotropic steel bridge decks by measuring the strain changes in the asphalt pavements on steel plate decks. In order to consider the applicability of this system, parametric FE analyses are carried out in which the types of crack, their positions and their lengths are ...

Analysis of Orthotropic Steel Plate Bridge Decks
Journal of the Structural Division, 1969A computer-oriented method for the analysis of orthotropic bridge decks is presented. The structure is idealized as a rectangular orthotropic plate which is continuous over simply supported, deformable floor beams. A finite element method is developed for the analysis of the idealized structure.

Blast Resistance of Steel Orthotropic Bridge Decks
Journal of Bridge Engineering, 2012AbstractThe main objectives of this study were to: (1) study the response of bridge decks to blast effects resulting from an explosion on the deck; and (2) develop efficient technologies and systems that can be used in design and construction of bridges to enable them to survive blast attacks without collapse.

Fatigue behaviour of orthotropic steel decks
1990Recently, some orthotropic steel bridge decks have suffered fatigue cracks For a better knowledge of this problem, the European Community promoted and financed collective research work in which seven laboratories in six European countries participated The Italian contribution to this research, deals with the experimental determination, on full scale ...
