Design and Optimization of the Bi-Directional U-Ribbed Stiffening Plate–Concrete Composite Bridge Deck Structure

Applied Sciences, 2023
The steel–concrete composite structure is widely used in civil engineering for large-span bridges. Orthotropic steel bridge decks (OSDs) have particularly gained popularity due to their excellent mechanical performance. To address cracking issues in OSDs

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
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

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, Volume 27, Issue 2, Page 1364-1382, April 2026.
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

Bending behavior of steel-UHPC composite bridge deck based on epoxy adhesive

Frontiers in Materials, 2022
Using ultra-high performance concrete (UHPC) as the pavement layer on the orthotropic steel deck (OSD) can greatly enhance the rigidity to solve the fatigue cracking of the steel deck and the resulting damage to the pavement layer. However, the thin UHPC

Fatigue resistance of the deck plate in steel orthotropic deck structures

Engineering Fracture Mechanics, 2018
Steel orthotropic decks in bridges and ferries have shown to be prone to fatigue cracking. A typical fatigue crack observed in these structures initiates at the root of the weld between the deck plate and stringer and grows into the deck plate. Due to limited fatigue test data available and the deviating characteristics of this type of crack as ...

Improvement of the Nonlinear Damage Mathematical Model for Steel Components in Bridge Under Complex Stress

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To investigate the relationship between load, damage, and fatigue life of complex engineering components under stress, this paper modifies the existing continuous nonlinear damage model based on the distortion energy density theory to reflect the usage and stress characteristics of Q345 steel components in bridges.

Fatigue Life Assessment of Orthotropic Steel Deck with UHPC Pavement

Journal of Engineering, 2017
In recent years, a number of large-span bridges with orthotropic steel decks were constructed in China. With increasing traffic volumes and higher wheel loads, many fatigue cracks developed at the welds and the edge of cut-out holes.
