Simple calculation model for evaluating the fire resistance of unreinforced concrete filled tubular columns
This paper presents a method for calculating the fire resistance of unreinforced axially loaded concrete filled circular hollow section columns, based on the guidelines of Eurocode 4 Part 1.2 for the fire design of composite columns. The different design approaches which are currently available worl...

The different design approaches which are currently available worldwide are reviewed in this paper, focusing in particular on the European code, which is discussed and analysed in depth.

The parametric studies investigate the main factors affecting the fire resistance of unreinforced concrete filled tubular (CFT) columns, such as the outer diameter, the thickness of the steel tube wall, the relative slenderness of the column at room temperature and the fire exposure time, widely covering the range of values which can be found in practice. From the results of these parametric studies, equations for obtaining the equivalent temperatures of steel and concrete are developed, and appropriate flexural stiffness reduction coefficients are integrated in the simple calculation model of Eurocode 4. The method presented here is valid for centrally loaded circular CFT columns filled with unreinforced normal strength concrete, and makes possible the calculation of slender columns, extending the current limitations in buckling length of the European codeThe authors would like to express their sincere gratitude to the Spanish "Ministerio de Ciencia e Innovacion" for the help provided through the Project BIA2009-9411 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 HormigónMinisterio de Ciencia e InnovaciónEuropean Regional Development FundRepositorio Institucional de la Universitat Politècnica de València Riunet20122012-09-01journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://riunet.upv.es/handle/10251/49662reponame:RiuNet.
