Prikazana je analiza djelovanja različitih slučajeva realnog požara za skladišnu halu. Primjenom modela zona za različita požarna opterećenja dobivene su temperaturne krivulje u funkciji vremena, koje su uzete kao djelovanje na nosivu čeličnu konstrukciju. Na temelju dobivenih temperaturnih krivulja modelirano je provođenje topline kroz osnovni materijal konstrukcije, te je utvrđen stupanj njene sigurnosti. Istraživanja se provode u okviru NAD-a (National Application Document).The analysis of various cases or real fire impact on a warehouse is presented. Temperature curves were obtained as a function of time by means of the zone model established for different fire loads. These curves were then used as actions influencing the load bearing steel structure. Based on such temperature curves, the passage of heat through the basic material of the structure was modeled, and the safety level of the structure was determined. These studies are conducted in the scope of the NAD (National Application Document)
