This study investigates the modal system identification of a steel cantilever beam using finite element method (FEM) simulations, which are validated by experimental testing. The beam was bolted to a reinforced concrete block and subjected to dynamic testing, where natural frequencies and mode shapes were extracted through Frequency Domain Decomposition (FDD). The experimental outcomes were compared with FEM predictions from SAP2000, and discrepancies were analysed using the Modal Assurance Criterion (MAC). A model updating procedure was applied, refining boundary conditions and considering sensor mass effects, which improved model accuracy. The updated FEM achieved closer agreement with frequency deviations reduced to less than 4% and MAC values above 0.9 for the first three modes. Beyond validation, the research links the updated FEM results with a Building Information Modelling (BIM) framework to enable the development of a digital twin of the beam. A workflow was designed to connect vibration monitoring data with BIM, providing visualisation of structural performance through colour-coded alerts. The findings confirm the effectiveness of FEM updating in generating reliable modal representations and demonstrate the potential of BIM-based digital twins for advancing structural condition assessment, maintenance planning and decision-making in civil engineering practice.<\/jats:p>","DOI":"10.3390\/buildings15213890","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T02:23:28Z","timestamp":1761704608000},"page":"3890","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Finite Element Model Updating of a Steel Cantilever Beam: Experimental Validation and Digital Twin Integration"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1661-3640","authenticated-orcid":false,"given":"Mohammad Amin","family":"Oyarhossein","sequence":"first","affiliation":[{"name":"CERIS, Civil Engineering Department, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2749-7796","authenticated-orcid":false,"given":"Gabriel","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"CERIS, Civil Engineering Department, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9127-7766","authenticated-orcid":false,"given":"Fernanda","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"CERIS, Civil Engineering Department, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1373-4540","authenticated-orcid":false,"given":"Hugo","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"CERIS, Civil Engineering Department, University of Aveiro, Campus Universit\u00e1rio de Santiago, 3810-193 Aveiro, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1347","DOI":"10.1109\/JSEN.2009.2026548","article-title":"Optical Fiber Accelerometer System for Structural Dynamic Monitoring","volume":"9","author":"Antunes","year":"2009","journal-title":"IEEE Sens.
