Forty-eight different configurations of wooden beams will be studied. All results were performed according to Eurocode 5, Parts 1-1 and 1-2. In this work, the load capability will be analysed according to the standards and compared with the elastic load of beam theory. The wooden beams studied will be made of glulam GL28H. Different exponential equations will be determined as representative of different beam geometries and loading conditions, which allows easy determination of the maximum load capability, rather than the standard methods, which are normally conservative and appropriate for use in design purposes with safety.<\/jats:p>","DOI":"10.37394\/232011.2025.20.9","type":"journal-article","created":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T10:35:31Z","timestamp":1750847731000},"page":"73-78","source":"Crossref","is-referenced-by-count":0,"title":["Design Equation for a Simply Supported Wooden Beam with Uniformly Distributed Load under Fire"],"prefix":"10.37394","volume":"20","author":[{"given":"Elza M.
