A state of the art review of modal-based damage detection in bridges: development, challenges, and solutions
(Multidisciplinary Digital Publishing Institute, 2017-05)
Article
Accés obertTraditionally, damage identification techniques in bridges have focused on monitoring changes to modal-based Damage Sensitive Features (DSFs) due to their direct relationship with structural stiffness and their spatial ... -
An acousto-ultrasonics pattern recognition approach for damage detection in wind turbine structures
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Comunicació de congrés
Accés obertThe design of a Structural Health Monitoring (SHM) systems is a requirement in the task of improving the safety and maintainability of the structures. Among the multiple techniques available for health monitoring, ... -
Application of optical fiber distributed sensing to health monitoring of concrete structures
(2013-08)
Article

Bridge damage detection based on vibration data: past and new developments
(2017-02)
Article
Accés obertOvertime, bridge condition declines due to a number of degradation processes such as creep, corrosion, and cyclic loading, among others. Traditionally, vibration-based damage detection techniques in bridges have focused ... -
Damage detection using principal component analysis applied to temporal variation of natural frequencies
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialFor preserving existing structures to the extent possible, vibration-based damage detection techniques are gaining more attention. In specific, tracking the changes in a structure’s natural frequencies employing the Principal ... -
Detection of structural changes through principal component analysis (PCA) and multivariate statistical inference
(2015)
Comunicació de congrés
Accés obertThis paper is focused on the development of a damage detection indicator that combines a data driven baseline model (reference pattern obtained from the healthy structure) based on principal component analysis (PCA) and ... -
Numerical damage identification of structures by observability techniques based on static loading tests
(2016-09)
Article
Accés obertThis article proposes the application of the observability techniques to deal with damage detection in bridges from their structural response under static loading tests. Unlike previous works based on a symbolic approach ... -
