Digital Image Correlation for Assessment of Bridges’ Technical State and Remaining Resource

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Bridges enable communications and transportation of goods nationally and internationally, underpinning economic and social activities, and thus they are pylons of our prosperity and mobility. Bridges worldwide are constantly subjected to physical wear, ageing, deterioration, hazards, environmental influences, and increased loading.

Analysis on Fatigue Crack of Orthotropic Steel Bridge Decks

, 2023
AbstractThrough the detection of the steel structure bridge for 7 years, the main distribution of cracks in steel box girder of steel structure bridge was presented. Through the numerical analysis of the steel box girder of steel structure bridge, the stress distribution of the diaphragms was obtained. The result of detection and the numerical analysis

Data‐Driven Fatigue Failure Probability Updating of OSD by Bayesian Backward Propagation

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
This study introduces a data‐driven approach for updating the fatigue failure probability of the orthotropic steel deck (OSD) using Bayesian backward propagation. The OSD in steel bridges is considered as a parallel system composed of two critical fatigue‐prone components, namely, the rib‐to‐diaphragm and rib‐to‐deck joints.

Analysis of Residual Stresses in Curved Cutouts of Steel Box Girder Transverse Diaphragms

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
In order to analyze the characteristics of cutting residual stress distribution at the arc‐shaped cutout of steel box girder diaphragm and to study its fatigue cracking mechanism. Taking Xia Zhang Bridge as the engineering background, this paper proposes a systematic method for calculating the residual stress field at the arc‐shaped cutout of the ...

Interaction between Viscoelastic Composite Beams and Vehicles by a Decoupled Method and Its Application in Engineering

Shock and Vibration, Volume 2024, Issue 1, 2024.
Asphalt mixture is a viscoelastic material composed of aggregates, asphalt mastics, and voids. Meanwhile, the dynamic interaction between vehicle and bridge makes asphalt deck pavement in a more complex stress state, leading to premature damage such as cracks and ruts during its operation service period.
