Enhancing Fire Resistance of Steel Bridge Girders Using External Fire Insulation

open access: yesKurdistan Journal of Applied Research, 2017
Fire in steel bridges can be a significant hazard; however, no provisions are specified for fire resistance of bridge structural members in current codes and standards.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

open access: yesStructural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

open access: yesStructural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

The Multi-Functional Modelling Shear Lag Method for Accurate Calculation of Static Response and Accordion Effect of Improved Composite Box Girders

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2023
The composite box girder with corrugated web and steel bottom plate (CW-SBS) is a kind of improved steel-concrete structures. The design of CW-SBS box girders needs the accurate method to calculate the working response and accordion effect in ...

Evaluating structural resistance and updating modeling uncertainties through testing

open access: yesStructural Concrete, EarlyView.
Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...

‘Grinning and bearing it’—A survey study exploring animal‐related injuries in UK and Irish veterinary students

open access: yesVeterinary Record Open, Volume 13, Issue 2, December 2026.
Abstract Background While veterinary surgeons are known to have particularly high rates of injury compared to other sectors, little is known about the rates of injury among veterinary students. This study aims to understand animal‐related injury rates, injury context and mechanisms, attitudes to reporting injuries, and resultant behaviour among UK and ...

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Evolution and Numerical Prediction of Fatigue‐Controlled Regions in Bolted–Welded Joints of Steel Truss Bridges

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
A three‐dimensional nonlinear refined finite element model for bolted and welded nodes in steel truss bridges identifies fatigue‐critical regions and governing mechanisms, enabling a fatigue life prediction method that supports safety assessment and durability design.

Numerical Investigation of Stress Intensity and Geometry Correction Factors in Welded Longitudinal Stiffener Details

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2654-2669, July 2026.
ABSTRACT The safe operation of aging steel railway bridges requires reliable fatigue assessment of welded structural details. Welded longitudinal stiffeners, while not directly loaded, influence structural stiffness and are susceptible to fatigue cracking at weld transitions.
