A Novel Sensitivity-Based Finite Element Model Updating and Damage Detection using Time Domain Response

TL;DR: In this paper , an exact and explicit sensitivity equation for structural parameters estimation using time-domain data is proposed. And the sensitivity equation provides a linear relation between the time history response and variation of structural parameters.

Damage diagnosis of high-rise buildings under variable ambient conditions using subdomain approach

TL;DR: An output-only damage diagnostic technique using the decentralized concept (subdomain-based) for high-rise buildings, employing the Vector form of the Autoregressive with exogenous input (VARX) model is developed.

Evaluation of matrix cracking in composite laminates based on anomaly indices

TL;DR: A Lamb waves-based automated method dealing with early detection and accurate evaluation of matrix cracking in composite laminates and an anomaly-detection method devoted to the quantification of the extent to which a laminate plate deviates from its intact state are developed.

Detection of structural damage through changes in frequency: a review

O.S. Salawu
TL;DR: The use of natural frequency as a diagnostic parameter in structural assessment procedures using vibration monitoring is discussed in this paper, based on the fact that natural frequencies are sensitive indicators of structural integrity.

A review of structural health monitoring literature 1996-2001

TL;DR: An updated review covering the years 1996 2001 will summarize the outcome of an updated review of the structural health monitoring literature, finding that although there are many more SHM studies being reported, the investigators, in general, have not yet fully embraced the well-developed tools from statistical pattern recognition.

Damage detection in structures: From mode shape to frequency response function methods

TL;DR: In this paper, a series of numerical simulations on a simple beam are made in order to compare various damage detection methods based on mode shape changes and a generalisation of these methods to the whole frequency ranges of measurement is proposed.

Structural damage identification using modal data. ii: test verification

TL;DR: In this article, a damage identification scheme is developed using the mode-based damage identification method described in an accompany paper, which is applied to the experimental data and the consequent results are compared.
