Sažetak
U radu je prezentirana primena prognoznog modela na bazi neuronskih mreža za predviđanje požarne otpornosti centrično opterećenih spregnutih stubova opožarenih sa svih strana. Primenom kompjuterskog programa FIRE analizirani su tri tipa spregnutih preseka: potpuno ubetonirani, delimično ubetonirani, cevkasti profil ispunjen betonom i referentni klasični AB stub. Analiziran je uticaj oblika, dimenzije preseka i intenzitet opterećenja na požarnu otpornost stubova. Rezultati numeričke analize poslužili su kao ulazni parametri za treniranje neuronske mreže.
