Finite element modelling of open longitudinal stiffener to crossbeam connection in OSD bridges for hot-spot stress determination

The phenomenon of fatigue in orthotropic steel deck (OSD) bridges is a predominant problem because of complexity of the prediction methods. In the past, many researchers have studied the fatigue behaviour of various details in OSDs via both experiments and Finite Element Modelling (FEM). In the present research, the connection of open stiffener...

Residual stress development in a repaired welded connection

Research shows that the fatigue strength of a Very High Strength Steel (VHSS) can be significantly negatively effected by welds in a structure. The fatigue lifetime may be extended after cracking occurs by means of fatigue crack repair. A better insight by means of Finite ElementModelling (FEM) can help in understanding the effects of a repair...
