Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, Volume 27, Issue 3, Page 3309-3324, June 2026.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Appearance Inspection‐Based Typical Damage Investigation of Concrete Curved Girder‐Type Bridges Subjected to Temperature and Vehicle Effect

Engineering Reports, Volume 8, Issue 5, May 2026.
Technical approach of the article. ABSTRACT This study focuses primarily on concrete curved girder‐type bridges, which are commonly used for urban roads and highways. Over the last two decades, practical experience in bridge engineering has shown that these bridges have unique mechanical and damage characteristics, unlike conventional straight bridges.

Anchorage System Contribution to Post‐Tensioned Bridge Collapse

Engineering Reports, Volume 8, Issue 5, May 2026.
This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

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,

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.

Infrastructure Anomaly Detection: A Study of the Settefonti Bridge Through Continuous OMA and Artificial Intelligence

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
This paper presents a novel approach for anomaly detection on the Settefonti Bridge by combining advanced operational modal analysis (OMA) technique with artificial intelligence. Ambient vibration data from accelerometers is processed using the covariance‐driven stochastic subspace identification (CoV‐SSI) method to extract modal parameters, which are ...
