Experimental and analytical investigations on the effect of steel fibers on the crack behavior and strength of dapped‐end connections

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

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

Structural 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

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

Experimental study on the influence of maintenance track position on vortex-induced vibration performance of a box girder suspension bridge

Frontiers in Built Environment, 2023
To study the influence of maintenance track on the vortex-induced vibration (VIV) performance of main girder, the VIV response and time history of surface pressure data of a section model were obtained by wind tunnel vibration and pressure measurements ...

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
