Description

The fire may occur anywhere and in any phase in the lifetime of a building .Fire resistance requirements should be based on the parameters influencing fire growth and development. For calculating the characteristic fire load, the characteristic fire load has to be determined using the table of EN 1991-1-2 Annex E.The aim of this paper is to present the methodology used in this tool and to show an example of application. The fire resistance of a steel beam submitted to compartment fires which supports a non-collaborating concrete slab in a compartment is estimated in case of an unprotected and a protected steel section. It will be possible, having this gas temperature, to calculate the temperature of a steel profile .Different results can be extracted from the software. The software package that will be used to perform this calculation is Ozone V2. Ozone V2 has been developed as a practical design tool to realize a performance based analysis of the behavior of simple steel elements in a compartment fire situation. The figures provided for the input data by the graphic interface are indicative values. They can be modified by the user who has full responsibility for the choice of these input data. A combination of a two and a one zone model is included. The criteria of transition offers to the user an automatic decision procedure to know whether a two or a one zone model is appropriated to the fire stage which is model.
