Test method to assess membrane layers fatigue response on orthotropic steel bridge decks

In order to adequately characterize the fatigue response of the various membranes with surrounding multilayer surfacing layers on orthotropic steel decks and collect the necessary parameters for FE modeling, the details of the cyclic Membrane Adhesion Tester (MAT) are introduced. The fatigue damage in membrane interface is related to the amount...

Experimental study of membrane fatigue response for asphalt multisurfacing systems on orthotropic steel deck bridges

In order to adequately characterize the fatigue response of the various membranes with surrounding multilayer surfacing layers on orthotropic steel decks and collect the necessary parameters for FE modeling, the details of the cyclic Membrane Adhesion Tester (MAT) are introduced.

High strength fibre reinforced concrete: Static and fatigue behaviour in bending

Recently, a number of high strength and ultra high strength steel fibre concretes have been developed. Since these materials seem very suitable for structures that might be prone to fatigue failure, such as bridge decks, the understanding of the static and fatigue bending behaviour is vital. In order to evaluate the bending behaviour of high and...

Renovation techniques for fatigue cracked orthotropic steel bridge decks

This dissertation presents the research into renovation techniques for orthotropic steel bridge decks. These techniques are needed to solve fatigue problems in the decks of these bridges, as several fatigue cracks have been detected in the deck structure of these bridges the last decade. A well-known example of fatigue cracks are those observed...

The behaviour of trough stiffener to crossbeam connections in orthotropic steel bridge decks

This article describes the behaviour and stress analysis of the crossbeams in orthotropic steel decks with continuous trapezoidal closed stiffeners. The trough stiffener to crossbeam connections, with or without cope holes, influence the behaviour of the crossbeam. The effects can be transferred to effective properties of a beam without cut outs...
