Innovative solutions for enhancing the fire resistance of slim-floor beams: Thermal experiments

[EN] Slim-floor beams have attracted the attention of designers in the last decades, owing to their ability for supporting intermediate loads without increasing the floor thickness. However, the behaviour of this type of beams at elevated temperatures has not been well understood yet. This paper pre...

However, the behaviour of this type of beams at elevated temperatures has not been well understood yet. This paper presents the results of an experimental campaign carried out at the testing facilities of the Universitat Politecnica de Valencia, Spain, where a series of slim-floor configurations were exposed to elevated temperatures into an electrical furnace. These tests had the novelty of considering different slim-floor beam typologies, as well as alternative ways for thermal protection, such as using intumescent coating, stainless steel or lightweight concrete into different cross-section parts. The test results were used to validate a finite element thermal model which allows for a detailed analysis of the cross-section thermal behaviour and the assessment of different ways to improve the slim-floor beam fire performance. The temperature results were subsequently imported into a computer code developed by the authors where a non-linear procedure was applied to obtain the plastic bending capacity of the cross-section at elevated temperatures. These final results reveal the different thermal performance of the analysed configurations and are used as a basis for providing design recommendations for future slim-floor developments.The authors would like to express their sincere gratitude to the Spanish "Ministerio de Economia y Competitividad" for the help provided through the Project BIA2015-67192-R and to the European Union through the FEDER funds.ElsevierDepartamento de Ingeniería de la Construcción y de Proyectos de Ingeniería CivilDepartamento de Mecánica de los Medios Continuos y Teoría de EstructurasEscuela Técnica Superior de Ingeniería IndustrialInstituto Universitario de Investigación de Ciencia y Tecnología del HormigónEuropean Regional Development FundMinisterio de Economía y CompetitividadRepositorio Institucional de la Universitat Politècnica de València Riunet20202020-02-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://riunet.upv.es/handle/10251/161596reponame:RiuNet.
