Durability performance of a high‐performance fiber‐reinforced concrete for bridge applications

Structural Concrete, EarlyView.
Abstract This paper investigates the durability performance of a coarse‐aggregate high‐performance fiber‐reinforced concrete (HPFRC) developed as a cost‐efficient material solution for precast bridge applications. A comprehensive experimental program was conducted to assess the resistance of the material to the principal deterioration mechanisms ...

REHABILITATION OF BOX GIRDER BRIDGE

Proceedings of International Structural Engineering and Construction, 2017
A large pre-stress continuous box girder bridge consists of two separate parts, ten spans deck and eight spans deck. The bridge was subjected to multiple airstrikes, which caused several damages. The most serious are the complete destruction of four conductive spans in the ten spans deck, the movement of the remaining six spans longitudinally by about ...

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

Structural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

A Functional Principal Component Analysis Framework for Vibration‐Based Structural Condition Assessment of Highway Bridge Spans

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT The management of lifespan and safety performance, aimed at ensuring the structural integrity and durability of highway infrastructure, has become an increasingly important area of research. In civil engineering, traditional methods for evaluating dynamic behavior, such as Operational Modal Analysis and the Peak Picking technique, often fall ...

Effective anchorage stress of prestressed tendons in PC girders under varying tensioning sequences [PDF]

Archives of Civil Engineering
In current design codes, the standardized anchorage stress of prestressed tendons in concrete girders is uniform, which presents a notable challenge in accurately assessing the effective anchorage stress of girders with varying span lengths.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Vertical Vibration Reduction of Maglev Vehicles Using Nonlinear Model Predictive Control

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT This work presents a novel nonlinear model predictive control (NMPC) strategy for high‐speed Maglev vehicles that explicitly incorporates mechanical suspension dynamics into the control model. Unlike conventional approaches, which often neglect the interaction between levitation magnet and car body motion, the proposed method enables ...

Cable Force Optimization Analysis of Cable‐Stayed Bridges Based on the Plant Growth Simulation Algorithm

Engineering Reports, Volume 8, Issue 8, August 2026.
A plant growth simulation algorithm (PGSA)‐based method optimizes cable forces in cable‐stayed bridges via parameter‐free global search and variable‐step parallel mechanism, achieving uniform force distribution, controlling bending moments and displacements, and enhancing structural performance while overcoming traditional algorithm limitations ...
