The main objective of this research was to assess the critical temperature and time of the studied beams. Other important goals of this research work were to investigate the influence of the cross-sections (C, lipped-I, R and 2R beams) and, above all, of the axial restraint (0, 0.45, 3, 7.5, 15, 30, \u221e kN\/mm) to the thermal elongation of the beam and the rotational restraint at beam supports (0, 15, 80, 150, 300, 1,200 and  \u221e kN.m\/rad) on the fire resistance of this kind of beams.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title>\n<jats:p>This paper still provides details of the simulation methodology for achieving numerical stability and faithful representation of detailed structural behaviour and compares the simulation and experimental results, including beam failure modes, measured beam axial forces and beam mid-span deflections.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>Good agreement between Abaqus simulations and experimental observations confirms that the finite element models developed with the Abaqus\/standard solver are suitable for predicting the structural fire behaviour of restrained cold-formed steel beams.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>The results showed above all that the effect of the stiffness of the surrounding structure seems to decrease with the increasing slenderness of the beams.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/jsfe-12-2016-026","type":"journal-article","created":{"date-parts":[[2017,1,9]],"date-time":"2017-01-09T06:02:39Z","timestamp":1483941759000},"page":"388-402","source":"Crossref","is-referenced-by-count":5,"title":["Experimental and numerical study on the fire response of cold-formed steel beams with elastically restrained thermal elongation"],"prefix":"10.1108","volume":"7","author":[{"given":"Luis","family":"La\u00edm","sequence":"first","affiliation":[]},{"given":"Jo\u00e3o Paulo C.","family":"Rodrigues","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"volume-title":"Standard User\u2019s Manual","year":"2010","author":"Abaqus\/CAE","key":"key2020121100053998800_ref011"},{"issue":"1","key":"key2020121100053998800_ref022","doi-asserted-by":"crossref","first-page":"96","DOI":"10.1016\/j.tws.2006.11.003","article-title":"Experimental investigation of cold-formed steel material at elevated temperatures","volume":"45","year":"2007","journal-title":"Thin-Walled Structures"},{"issue":"10","key":"key2020121100053998800_ref017","doi-asserted-by":"crossref","first-page":"1271","DOI":"10.1016\/S0141-0296(99)00082-6","article-title":"Finite element modeling of bolted connections between cold-formed steel strips and hot rolled steel plates under static shear loading","volume":"22","year":"2000","journal-title":"Engineering Structures"},{"key":"key2020121100053998800_ref001","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.firesaf.2011.12.010","article-title":"Fire resistance of steel columns with restrained thermal elongation","volume":"50","year":"2012","journal-title":"Fire Safety Journal"},{"issue":"10\/11","key":"key2020121100053998800_ref016","first-page":"771","article-title":"Local\/distortional mode interaction in cold-formed steel lipped channel beams","volume":"48","year":"2010","journal-title":"Thin-Walled Structures"},{"volume-title":"Eurocode 1- Actions on Structures - Part 1-2: General Actions - Actions on Structures Exposed to Fire","year":"2002","author":"EN1991-1.2","key":"key2020121100053998800_ref025"},{"key":"key2020121100053998800_ref013","article-title":"Design of steel structures","volume-title":"General Rules and Rules for Buildings","author":"EN1993-1.1","year":"2004"},{"volume-title":"Design of steel structures.
