Significant temperature variations in RC elements can affect their natural frequencies and modulus of elasticity or generate abnormal stress levels, potentially leading to structural damage. Data from thermal monitoring systems are invaluable for testing and validating numerical methodologies for estimating internal thermal responses and aiding in prevention\/maintenance decision making. Despite its importance, few experimental outdoor data on the internal and external temperatures of concrete structures are available. This study presents a comprehensive dataset from a 120-day temperature-monitoring campaign on a 1.2 m long reinforced-concrete slab-on-I-beam model under tropical conditions in Bucaramanga, Colombia. The monitoring system measured the internal temperatures at 40 points using embedded thermocouples, while the surface temperatures were recorded with handheld and drone-mounted thermal cameras. Simultaneously, the ambient temperature, solar radiation, rainfall, wind velocity, and other parameters were monitored using a weather station. The instrumentation ensured the synchronization and high spatial resolution of the thermal data. The data, collected at 30 min intervals, are openly available in CSV format, offering valuable resources for validating numerical models, studying thermal gradients, and enhancing structural health-monitoring frameworks.<\/jats:p>","DOI":"10.3390\/data10020021","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T05:55:22Z","timestamp":1738648522000},"page":"21","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["An Open Database of the Internal and Surface Temperatures of a Reinforced-Concrete Slab-on-I-Beam Section"],"prefix":"10.3390","volume":"10","author":[{"given":"Pedro","family":"Cavadia","sequence":"first","affiliation":[{"name":"Escuela de Ingenier\u00eda Civil, Universidad Industrial de Santander, Bucaramanga 680002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5654-948X","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Benjumea","sequence":"additional","affiliation":[{"name":"Escuela de Ingenier\u00eda Civil, Universidad Industrial de Santander, Bucaramanga 680002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2895-9374","authenticated-orcid":false,"given":"Oscar","family":"Begambre","sequence":"additional","affiliation":[{"name":"Escuela de Ingenier\u00eda Civil, Universidad Industrial de Santander, Bucaramanga 680002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4264-9524","authenticated-orcid":false,"given":"Edison","family":"Osorio","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda Civil, Universidad Antonio Nari\u00f1o, Bogot\u00e1 111321, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8388-3886","authenticated-orcid":false,"given":"Mar\u00eda A.","family":"Mantilla","sequence":"additional","affiliation":[{"name":"Escuela de Ingenier\u00edas El\u00e9ctrica, Electr\u00f3nica y de Telecomunicaciones, Universidad Industrial de Santander, Bucaramanga 680002, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.engstruct.2012.04.003","article-title":"Behavior of precast prestressed concrete bridge girders involving thermal effects and initial imperfections during construction","volume":"42","author":"Lee","year":"2012","journal-title":"Eng.
