Anchorage System Contribution to Post‐Tensioned Bridge Collapse
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

Life Time Evaluation of Orthotropic Steel Bridge Decks [PDF]
The fatigue performance of orthotropic steel bridge decks depends on the magnitude and number of stress cycles applied, and the deck details. The stress induced in a deck plate will be reduced by the presence of a stiff surfacing material.

Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a
