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

Analysis of Fatigue Performance of U-Rib to Deck Connections in Orthotropic Steel Bridge Structures [PDF]
The stress condition of the transverse rib, bridge deck, and crossbeam in orthotropic steel bridge decks (OSBD) is complicated. Existing fatigue test specimens and the fatigue performance of components in OSBD differ significantly.

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
