Finite element analysis of the closed stiffener to crossbeam connection in OSDs using the hot spot stress approach

An Orthotropic Steel Deck (OSD) is suspectable to fatigue and this forms an important design criterium. In this research the rib-to-crossbeam connection with a cope hole is studied using Finite Element Methods (FEM). The fatigue assessment is performed with the hot spot stress method making use of surface stress extrapolation. Two fatigue cracks...

Prediction of residual stress of an orthotropic plate due to welding

Orthotropic steel decks are widely used in bridge construction nowadays, especially in case of long span bridges. One of the main problems of bridges that utilize this technology is the susceptibility to fatigue failure. Cyclic loading due to wheel loads, in combination with the complex network of welded details, make such types of decks prone...
