Monitoring of temperature gradient development of highway concrete bridge

MATEC Web of Conferences, 2017
Thermal effect is one of very important from the large bridge design procedure point of view. Especially vertical temperature gradient is being crucial. There were realized some research works of the thermal effects monitoring on the concrete bridges in ...

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

Structural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.

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 ...

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 ...
