[more ▼] The methodologies that are used for analysing the fire behaviour of a structure that is subjected to a uniform thermal situation cannot be applied when the fire is localised. The concept of "zoning" can be applied: the structure is divided into several zones in which the situation is approximated as uniform. It is shown here that this division can lead to spurious forces in the structure. The structural code of the first author has been adapted in order to accommodate a continuous spatial variation of the fire environment. A series of uncoupled 2D thermal analyses is performed along the length of the beam finite elements and a series of ID thermal analyses is performed across the thickness of the shell finite elements. After a discussion of the concept and the particularities dictated by the continuous thermal environment, the methodology utilised is explained and is shown in an example consisting of a composite steel concrete car park subjected to a localised fire of the type given in Eurocode 1.

[more ▼] The methodology implemented in the tool OZone V2 to design steel elements submitted to compartment fires is presented. Input needed to define a fire compartment are first quoted. The procedure to define the design fire is then explained. This procedure enables to take into account the benefits of active measures on the fire safety. The combined use of a two- and a one-zone model is then presented. A particular attention is given to the criteria of choice of the model and to the different scenarios that can occur. The calculation of steel element temperature is then explained. The proposed procedure takes into account the localised effect of a fire with the help of Hasemi's model. The fire resistance is then calculated with the EUROCODE 3 methods. An application is finally presented. (C) 2003 Elsevier Science Ltd. All rights reserved.

[more ▼] A thorough analysis has been performed to evaluate SAFIR release 1.3 through a set of examples presented by Wyckström in the paper "An evaluation scheme of computer codes for calculating temperature in fire exposed structures - two dimensional analysis". The results of SAFIR 1.3 have been compared with the results obtained by TASEF, or to analytical solution when available. The results of SAFIR 1.3 compare well with the analytical solutions and, with few exceptions, with those of TASEF. [less ▲] Detailed reference viewed: 65 (1 ULg) |
