Fire resistance evaluation for a steel hall transverse frame depending on the simplification degree of the computational model applied

: It is presented in detail how the selection of a structural model describing the behaviour of a steel hall transverse frame when subject to ﬁre exposure in a more or less complex way may aﬀect the ﬁre resistance evaluation for such a frame. In the examples compiled in this paper the same typical one-aisle and single-story steel hall is subjected to simulated ﬁre action, each time following the same ﬁredevelopmentscenario.Aresultantﬁreresistanceisidentiﬁedindividuallyineachcase,usingvariouscomputationalmodels,onanappropriatestaticequilibriumpathobtainednumerically.Theresulting estimatesvary,notonlyinthequantitativesense,butalsointermsoftheirqualitativeinterpretation.Itisshownthatthegreaterthesimpliﬁcationofthemodelused,themoreoverstatedtheestimatedﬁre resistanceisinrelationtoitsrealvalue.Suchanoverestimationseemstobedangeroustotheuser,asitgiveshimanillusorybutformallyunjustiﬁedsenseoftheguaranteedsafetylevel
