Experimental and numerical validation of an innovative OSD strengthening with a bonded and bolted plate

For the renovation of the Suurhoff bridge, Arup decided to design and propose a new, innovative strengthening scheme, which improves the fatigue performance of the bridge deck and extends the design life of the bridge by at least 15 years. In this strengthening scheme, a steel plate is placed on top of the existing deck plate with a layer of...

Fatigue assessment of rail track detail on movable bridge in Estonia based on 2D/3D Finite Element Modelling using hot-spot stresses

There are several methods to perform fatigue assessment as described by the Eurocode 3 and the International Institute of Welding (IIW). The codes establish the relation between stress ranges and their respective number of cycles until failure of the detail. This method is called S-N curves, however this is based mainly on nominal stresses. A...
