Structural Health Monitoring of a Unidirectional Isolation Bridge: Bidirectional Seismic Behavior, Stochastic Model Updating, and Prediction

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 759-780, March 2026.
ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Temperature field characteristics of concrete box girders in rigid-frame bridges based on fine simulation and monitoring

Case Studies in Thermal Engineering
The non-uniform temperature distribution in long-span double-box single-cell concrete box girder bridges can lead to reduction in structural bearing capacity and temperature-induced diseases.

Stress Corrosion Tests for Prestressing Steels—Part 2: Susceptibility of Quenched and Tempered Wires—Influence of Chromium

Materials and Corrosion, Volume 77, Issue 1, Page 36-45, January 2026.
Cr‐alloyed quenched and tempered prestressing steel wires were found to be as highly susceptible as non‐Cr‐alloyed ones. This finding is in contrast to the known literature. A newly developed and reproducible method for assessing susceptibility to hydrogen‐induced stress corrosion cracking was used.

Stress Evaluation for Segmental Concrete Box Girder Diaphragm [PDF]

E3S Web of Conferences, 2018
The box girder component is a major breakthrough in the construction field for its effective geometry behavior and high torsional rigidity. However, the analysis and design of the box girder are complex due to its three dimensional behavior i.e. torsion, distortion and bending in longitudinal and transverse direction.

Study on the Crack Propagation Behavior and Patterns of High‐Speed Railway Bridges Under High‐Speed Train Loading

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study focuses on simply supported railway box girder bridges with pre‐existing cracks under high‐speed train loading. A vehicle–bridge coupled vibration model is established, and three‐dimensional dynamic stress intensity factors at the crack tip under various loading conditions are obtained using the interaction integral method.

Study on the influence of damping plates on structural vibration and radiation characteristics of the railway box girder

Journal of Low Frequency Noise, Vibration and Active Control, 2021
The influence of damping plates on structural vibration, noise and the contribution of the box girder bridge panels was analysed using the model test and numerical calculation methods. In this paper, a 1/10 scale box girder model test system was designed

The Effect and Mechanical Mechanism of Intermediate Diaphragms in Prefabricated T‐Beam Bridges

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Current bridge design codes stipulate that prefabricated T‐beam bridges must include intermediate diaphragms, with spacing not exceeding 10 m. However, the construction of these diaphragms entails extensive overhead work, elevated safety risks, and significant challenges in quality control.

Reliability Assessment of Simply Supported Beam Bridge Structural Performance Based on Load Tests

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Currently, bridge load tests use the verification coefficient to evaluate the structural performance of bridges in China, but this method is unsuitable. This paper presents a method that utilizes reliability to compare the actual bridge structural performance with the designed performance. Reliability functions for strain and deflection in load testing
