title = "Sheet steel - mineral wool fire protection of steel columns",
abstract = "The paper summarizes the results of fire tests of steel columns protected by various number of mineral wool layers separated by aluminium foils and covered by sheet steel box. The influence of different fixing methods and the cracks appearing in the corners of the columns of the efficiency of the protection system were studied. The efficiency of different protection systems is compared by the aid of virtual thermal resistances. The aim of the study was to develop a box type fire protection system which could be fabricated industrially to ensure better quality and lower costs.",
