A novel asynchronous-pouring-construction technology for prestressed concrete box girder bridges with corrugated steel webs

Structures, 2020
Owing to the superior mechanical performance and material efficiency, the combination of prestressed concrete (PC) slabs and corrugated steel webs (CSW) as PC girder with CSWs (PCGCSW) is extensively applied to railway and highway bridges.

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,

Robust Design Optimization for Low-Cost Concrete Box-Girder Bridge

Mathematics, 2020
The design of a structure is generally carried out according to a deterministic approach. However, all structural problems have associated initial uncertain parameters that can differ from the design value.

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.

The Analysis Of Reinforced Concrete Box Girder Viaduct Defects and Their Estimation

The Baltic Journal of Road and Bridge Engineering, 2012
The article describes the main damages of box girder viaducts constructed in Lithuania and discusses the reasons for their occurrence. Several viaducts are examined in more detail with regard to their design data and experimental results. Using finite element software “Midas Civil” the distribution of the main stresses was determined in the box and ...

Evaluation of Bearing Capacity of Assembled Prestressed Concrete Continuous Box‐Girder Bridges Based on Virtual Loading of Influence Lines

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
In order to accurately identify the influence line from the dynamic response of vehicle‐induced bridges to rapidly evaluate bridge bearing capacity, an influence line identification method based on variational mode decomposition (VMD) and the Tikhonov regularization method is proposed.
