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>

Evaluation on root-deck fatigue of orthotropic steel bridge deck

Journal of Constructional Steel Research, 2013
Abstract Orthotropic steel decks are widely used in cable-supported bridges. The fatigue cracks in trough-deck welded joints have been detected in some bridges in China. In this paper, the finite element method (FEM) is applied to evaluate fatigue durability of the root-deck fatigue in the trough-deck welded joints over the diaphragms.

Blast Resistance of Steel Orthotropic Bridge Decks

Journal of Bridge Engineering, 2012
AbstractThe 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.

INFLUENCE SURFACES FOR ORTHOTROPIC STEEL BRIDGE DECKS.

Proceedings of the Institution of Civil Engineers, 1975
An analytical method to produce influence surfaces for stiffened steel bridge decks is described. It uses dynamic relaxation to solve the finite difference form of the orthotropic small deflexion plate equations and employs A variable orthogonal mesh to ensure maximum economy of computer time and storage.

Stress concentration in steel bridge orthotropic decks

Journal of Constructional Steel Research, 2005
Abstract The structural behaviour of orthotropic steel decks is characterized by the complex interaction between its components (deck plate, ribs and floorbeams) and also by the interaction between the structure, the pavement and the vehicle’s wheels tyres.

Analysis of Orthotropic Steel Plate Bridge Decks

Journal of the Structural Division, 1969
A 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.

Fatigue Assessment of Orthotropic Steel Bridge Decks

1990
Fatigue 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.

Wearing Surfaces for Orthotropic Steel Bridge Decks

Transportation Research Record: Journal of the Transportation Research Board, 1999
In the state of Alaska, a six-span 884.5-m orthotropic steel bridge crosses the Yukon River at a 6 percent grade. The bridge is on a gravel road, it has a roadway width of 9.2 m, and the orthotropic steel deck is supported by two steel box girders 154.9 cm wide and 414.0 cm deep. The structure is expected to support the oil pipeline, a future gas line,

Numerical Evaluation of Toe-Deck Fatigue in Orthotropic Steel Bridge Deck

Journal of Performance of Constructed Facilities, 2015
AbstractSome toe-deck crack cases in China have been reported after about 10 years of service in suspension and beam bridge steel orthotropic decks with trough stiffeners. In this paper, a reference stress method used in design practice and a hot-spot stress method provided by the International Institute of Welding are used to investigate toe-deck ...

Durability of asphaltic pavements on orthotropic decks of steel bridges

Journal of Constructional Steel Research, 1987
Abstract By using a simplified model for calculating the action effects in asphaltic pavements on orthotropic decks of steel bridges and by comparing the results with data from inspection reports, it has been possible to define the ultimate resistance of these pavements.
