A method that can assess a bridge\u2019s condition in real time is urgently needed. The main factors that hinder bridge condition assessment are the uncertain operational environments. A new moving principal component analysis (MPCA)-based method is developed for structural damage detection in bridges in operational environments in this paper. Two main operational environmental factors, the environmental temperature and traffic loads, are studied in the assessment process to verify the robustness and practicality of the proposed method. The numerical and experimental results show that the proposed method is effective and accurate in assessing the bridge\u2019s condition in operational environments.<\/jats:p>","DOI":"10.3390\/s24020383","type":"journal-article","created":{"date-parts":[[2024,1,9]],"date-time":"2024-01-09T03:36:58Z","timestamp":1704771418000},"page":"383","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Moving-Principal-Component-Analysis-Based Structural Damage Detection for Highway Bridges in Operational Environments"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8852-4869","authenticated-orcid":false,"given":"Ye","family":"Yuan","sequence":"first","affiliation":[{"name":"School of Civil and Environmental Engineering, University of Technology Sydney, Ultimo, NSW 2007, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5083-9320","authenticated-orcid":false,"given":"Xinqun","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Civil and Environmental Engineering, University of Technology Sydney, Ultimo, NSW 2007, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Li","sequence":"additional","affiliation":[{"name":"School of Civil and Environmental Engineering, University of Technology Sydney, Ultimo, NSW 2007, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1225","DOI":"10.1177\/1475921717750047","article-title":"Structural health monitoring: Closing the gap between research and industrial deployment","volume":"17","author":"Cawley","year":"2018","journal-title":"Struct.
