Application of the SAFIR Computer Program for Evaluating Fire Resistance

摘要

In this paper, the application of the computer program SAFIR to study the behaviour of a steel framed structure exposed to fire is illustrated. The salient features of the computer program SAFIR are described. Using the computer program, a case study is carried out on a four storey steel framed structure under various fire protection configurations. Results from the analysis are used to compare the behaviour of individual structural elements with that of a structural element, acting as part of the overall frame. It is shown that the fire resistance is enhanced when the overall structural behaviour concept is considered, rather than the present concept that is based on a single member.
