Safety of steel structures under the influence of fire loads
The paper presents an analysis of the influence of various types of actual fire loads upon a given industrial structure - a steel warehouse. Six different fire loads were simulated with different quantities of combustible material and by varying floor surfaces covered by combustible material. Using a zone model, based on an approximate formulation, for different fire loads, obtained by varying the surface of ventilation openings, it was possible to obtain the temperature curves as a function of time which were used as the temperature load upon the supporting steel structure. Model of transient non-linear heat transfer was used to analyse the influence of the shape of the cross-section of the steel structure was analysed by using in case of standard fire and temperatures were determined for six different cases of actual fires for specific cross-sections of a steel structure (non-protected and protected).
actual fire load; transient non-linear heat transfer; temperature curves; section factor
