Focusing on the first step to improve the performance of vibration-based SHM strategies, the extracted features should be robust to noise, sensitive to the presence of a specific type of damage. Further, damage should induce patterns that are distinguishable from environmental and operational variabilities and other forms of damage such as ageing phenomena. In this paper, the problem is framed as an outlier detection problem and the the use of different modal parameters as Damage Sensitive Features (DSFs) is investigated, evaluating them based on the detection performance of an unsupervised One-Class Support Vector Machine (OCSVM) classifier. In particular, an artificial dataset is generated from the calibrated numerical model of a three-storey steel frame structure in different damage scenarios. The methodology is validated against available experimental data. For the case investigated the natural frequencies were sensitive to damage and robust to noise.<\/jats:p>","DOI":"10.1088\/1742-6596\/2647\/18\/182043","type":"journal-article","created":{"date-parts":[[2024,6,28]],"date-time":"2024-06-28T08:25:38Z","timestamp":1719563138000},"page":"182043","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Investigation of modal damage-sensitive features of a scaled three-storey steel frame for vibration-based damage detection."],"prefix":"10.1088","volume":"2647","author":[{"given":"Francesca","family":"Marafini","sequence":"first","affiliation":[]},{"given":"Giacomo","family":"Zini","sequence":"additional","affiliation":[]},{"given":"Alberto","family":"Barontini","sequence":"additional","affiliation":[]},{"given":"Silvia","family":"Monchetti","sequence":"additional","affiliation":[]},{"given":"Michele","family":"Betti","sequence":"additional","affiliation":[]},{"given":"Gianni","family":"Bartoli","sequence":"additional","affiliation":[]},{"given":"Nuno","family":"Mendes","sequence":"additional","affiliation":[]},{"given":"Alice","family":"Cicirello","sequence":"additional","affiliation":[]}],"member":"266","reference":[{"volume":"R9314","year":"1993","author":"Rytter","key":"JPCS_2647_18_182043bib1"},{"key":"JPCS_2647_18_182043bib2","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1098\/rsta.2000.0717","article-title":"Vibration-based structural damage identification.
