Large‐scale tests of 50‐year‐old prestressed concrete bridge girders

Structural Concrete, EarlyView.
Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

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,

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.

Preliminary Study on the Damping Effect of a Rotational Inertia Particle Damper Considering the Explosion Response of Continuous Concrete Bridges

Buildings, 2023
The possibility of blast impact loads acting on bridge structures is gradually increasing. The local and entire explosion response law of a concrete box girder bridge is still unclear, and anti-explode devices for reducing the entire explosion response ...
