Vibration-based damage detection of buildings using a decision-tree-based algorithm [PDF]

Numerical Methods in Civil Engineering, 2023
Previous studies revealed that traditional methods of damage detection (e.g., visual inspection) are time-consuming and require large monetary resources.

A robust FRF damage indicator combined with optimization techniques for damage assessment in complex truss structures

Case Studies in Construction Materials, 2022
Vibration-based damage detection tools are frequently employed because of their advantages over other non-destructive techniques. This paper presents an improved Frequency Response Function (FRF) indicator for damage identification in complex structures.

Numerical and Experimental Verification of a Multiple-Variable Spatiotemporal Regression Model for Grout Defect Identification in a Precast Structure

Sensors, 2020
Due to the increased service life, environmental corrosion, unreasonable construction, and other issues, local defects inevitably exist in civil structures, which affect the structural performance and can lead to structural failure.

Combined simulation of fatigue crack nucleation and propagation based on a damage indicator [PDF]

Fracture and Structural Integrity, 2016
Fatigue considerations often distinguish between fatigue crack nucleation and fatigue crack propagation. The current work presents a modeling approach utilizing one Fatigue Damage Indicator to treat both in a unified way.

Output-Only Damage Detection of Shear Building Structures Using an Autoregressive Model-Enhanced Optimal Subpattern Assignment Metric

Sensors, 2020
This paper proposes a novel output-only structural damage indicator by incorporating the pole-based optimal subpattern assignment distance with autoregressive models to localize and relatively assess the severity of damages for sheared structures ...

Intracochlear Recordings of Electrophysiological Parameters Indicating Cochlear Damage [PDF]

Otology & Neurotology, 2010
The pathophysiologic mechanisms resulting in hearing loss during electrode implantation are largely unknown. To better understand the functional implications of electrode implantation, we recorded the effects of cochlear damage on acoustically evoked intracochlear measurements using normal-hearing gerbils.

Structural Damage Localization under Unknown Seismic Excitation Based on Mahalanobis Squared Distance of Strain Transmissibility Function

Applied Sciences, 2022
Due to the unpredictability of seismic excitation, the data-driven damage identification method, which only depends on the monitoring response data, has a good development prospect in structural health monitoring.

Damage Detection of Wooden Beams Based on the Modal Strain Energy Change and Evidence Theory

BioResources, 2023
A damage detection and localization method for wooden beams was proposed based on the modal strain energy (MSE) change and evidence fusion. The fused damage indicator was deduced using the first three mode shapes of the wooden beams before and after ...

Computer-Vision and Machine-Learning-Based Seismic Damage Assessment of Reinforced Concrete Structures

Buildings, 2023
Seismic damage assessment of reinforced concrete (RC) structures is a vital issue for post-earthquake evaluation. Conventional onsite inspection depends greatly on subjective judgments and engineering experiences of human inspectors, and the efficiency ...
