Experimental Study on Reasonable Steam Curing Scheme of Prefabrication Box Girder

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
The assembly‐line production mode was adopted to meet the production demands of prefabricated box girders for the Haiyan line. The steam curing method was introduced to accelerate concrete strength development, allowing the prestressing tension requirements of the box girders to be met quickly.

Safety Performance Evaluation of a Novel Portable Concrete Barrier Based on Vehicle Impact Test

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Portable concrete barriers (PCBs) are modular structures widely used to separate traffic lanes from construction zones. However, these barriers often exhibit insufficient structural safety to effectively block intruding vehicles, leading to severe casualties.

A Two‐Stage GAF‐CNN Anomaly Detection and Conditional Residual Transformer Data Imputation Method for Crack‐Width Monitoring Data

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
In structural health monitoring (SHM), crack‐width measurements are critical indicators of damage severity and serviceability in concrete structures. However, field data are frequently affected by sensor drift, environmental noise, and transmission errors, resulting in anomalous or missing segments that undermine safety assessments.

A Noncontact Methodology for Disengagement Monitoring of High‐Speed Railway Bridge Bearings Based on Bearing‐to‐Beam Displacement Relation Under Round‐Trip Trains

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Bearings are critical components of bridges and are susceptible to various forms of deterioration under the action of traffic loads and complex environmental conditions. Existing methods for assessing the condition of bearings, including visual inspections, force sensors, cameras, and vibration sensors, still present challenges in accurately locating ...

Dynamic Response Analysis of the Coupled Vibrations of Vehicle–Curved Bridge Systems With or Without Diaphragms

Shock and Vibration, Volume 2026, Issue 1, 2026.
This study investigates the effects of diaphragms on vehicle–curved bridge coupled vibrations by establishing a finite element model of a three‐span continuous girder curved bridge with a single‐box double‐cell cross section and a curvature radius of 250 m, and a vehicle moving system model in COMSOL.
