Application of neural networks to the prediction of the compressive capacity of corroded steel plates

Frontiers in Built Environment, 2023
The application of artificial neural network approaches has been successful in solving complex civil engineering problems, such as damage detection and structural member capacity prediction.

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

Structural 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

Evaluating structural resistance and updating modeling uncertainties through testing

Structural 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

Veterinary 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

Earthquake 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

Engineering 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

Fatigue &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.

Model studies on plate girders

The Journal of Strain Analysis for Engineering Design, 1983
Tests on eighteen small scale models which simulate the elastic and post-buckling behaviour of plate girders when subjected to shear loading are reported and discussed. The models were fabricated of steel and Araldite; the major aim was to assess whether small scale models can be employed to study shear buckling problems.
