A new concept of orthotropic steel bridge deck

Structure and Infrastructure Engineering, 2008
A new concept of orthotropic steel bridge deck is proposed to improve its durability and economy. It is suggested to hot-roll the longitudinal ribs. Thus, the ribs can be made larger and with a more effective cross section that is not possible for cold bent ribs.

Refurbishment of orthotropic steel bridge decks by bolted solutions

IABSE Reports, 2019
<p>An increasing number of steel road bridges in Germany, but also in Europe and North America, show severe fatigue damages induced by the increase in heavy traffic loads. In addition, these road bridges from the 1960s to the 1980s were executed with fatigue-critical details, which are no longer state of the art today.

ANALYSIS OF ORTHOTROPIC STEEL BRIDGE DECKS BY A STIFFNESS METHOD.

Proceedings of the Institution of Civil Engineers, 1973
A stiffness method of analysis of orthotropic steel bridge decks having open type ribs (torsionally soft) is developed incorporating the basic theory of eccentrically stiffened plates. The method is readily programmed to obtain the desired solution from the computer.

Concrete overlay of movable steel orthotropic bridge decks

Steel Construction, 2009
AbstractThe deck plate of steel orthotropic bridges is loaded in fatigue by traffic. Increases in both the traffic intensity and the magnitude of the wheel loads have caused premature fatigue cracking of steel bridges in the Netherlands, mostly on very busy motorways.

Orthotropic Steel Plates for Bridge Deck Replacement

1990
A large number of our nation's bridges have reached the age where serious deterioration requires replacement of the roadway deck. Where first cost is the determining factor, replacement in kind—usually reinforced concrete—is the normally accepted method.

Sandwich system for renovation of orthotropic steel bridge decks

Journal of Sandwich Structures & Materials, 2010
A sandwich system of two steel faces and a polyurethane core is studied as a renovation system for orthotropic steel bridge decks. An experimental program has been carried out aiming to better understand the sandwich beam flexural behavior. The temperature significantly affects the sandwich flexural behavior.

Construction of Asphalt Pavement for Orthotropic Steel Deck Bridge

2021
The article describes the methodology of calculating and designing of the pavement on the hoist superstructure with orthotropic steel deck of the roadway. This work is a part of the planned overhaul of unique road bridge across the Severnaya Dvina River in Arkhangelsk. In accordance with current standards, the thickness of the new asphalt pavement must

A study of open rib orthotropic steel bridge decks

2022
Steel orthotropic bridge decks (SOBD) have been widely used for long span bridges, but have not been heavily employed for short and medium span bridges that encompass the majority of highway bridges in the United States. The lack of robust standards and high initial cost of fabrication have deterred the widespread utilization of these bridge decks ...

Fatigue Properties Estimates of Orthotropic Deck on Steel Bridges

Applied Mechanics and Materials, 2011
For estimating the fatigue properties of orthotropic deck bridges, a finite element analysis method was provided. In the method, the models of orthotropic decks steel bridge were established by using Midas and Ansys finite element software respectively, the Midas software has tracked two kinds of live load positions that corresponding to maximum and ...

Fire of Steel Plate Girder Bridge With an Orthotropic Deck

IABSE Reports, 2016
<p>A huge fire on Lazienkowski Bridge across Vistula River - one of the most important bridges in the center of Warsaw – capitol of Poland occurred on 14 of February 2015. The bridge was built in 1972-74as full steel structure with three wooden service decks between girders.
