Damage Identification Method Using Additional Virtual Mass Based on Damage Sparsity

open access: yesApplied Sciences, 2021
Damage identification methods based on structural modal parameters are influenced by the structure form, number of measuring sensors and noise, resulting in insufficient modal data and low damage identification accuracy.

An Improved Static Residual Force Algorithm and Its Application in Cable Damage Identification for Cable-Stayed Bridges

open access: yesApplied Sciences, 2022
For cable-stayed bridges, cables are very important components to maintain the safety of the whole bridge structure. It is well-known that change in cable force reflects the health of the cable-stayed bridge.

Artificial-Neural-Network-Based Surrogate Models for Structural Health Monitoring of Civil Structures: A Literature Review

open access: yesBuildings, 2022
It is often computationally expensive to monitor structural health using computer models. This time-consuming process can be relieved using surrogate models, which provide cheap-to-evaluate metamodels to replace the original expensive models.

Damage identification after seismic events through damage indexes

open access: yesProcedia Structural Integrity, 2023
The seismic events that have affected the building heritage over the past years have highlighted the vulnerability and the huge direct and indirect losses associated with earthquakes. The research of methodologies able to evaluate the post-earthquake damage state is clearly decisive to allow a quick and safe estimation of the building state in the ...

Damage Identification of Turnout Rail through a Covariance-Based Condition Index and Quantitative Pattern Analysis

open access: yesInfrastructures, 2023
Subjected to complex loadings from the wheel–rail interaction, turnout rail is prone to crack damage. This paper aims to develop a condition evaluation method for crack-alike damage detection of in-service turnout rail.

Interferometric Techniques in Structural Damage Identification [PDF]

open access: yesShock and Vibration, 2012
This paper describes several interferometric techniques and their applications in structural damage identification. With that objective in mind, damaged aluminum beams with clamped-free and free-free boundary conditions are analyzed. Different damages cases are inflicted by creating small cuts perpendicular to the beams longitudinal axis, being the ...
