In the CEC Agreement 7210 PR-378 was presented a benchmark between different software capable to predict the behaviour of a steel frame exposed to fire.

Abstract
In the CEC Agreement 7210 PR-378 was presented a benchmark between different software capable to predict the behaviour of a steel frame exposed to fire. The finite element software used in the analyses were ANSYS, ABAQUS and SAFIR. The original aim of the benchmark was to shown that the software were capable to replicate the failure mode so that post-local failure stage can be analysed. In addition to these results, in this paper the analysed model is studied through another finite element software, STRAND7, in order to evaluate its capability to predict the behaviour of the steel frame exposed to fire using a simplified constitutive law of steel at high temperatures. In fact in the former software the constitutive law used was defined according to information provided by Eurocode 1993-1-2, while in STRAND7 only an elastic-perfectly plastic behaviour of the steel at high temperatures can be defined. The evidence of the comparison will be discussed in this benchmark.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
