How do I calculate fire resistance of cold-formed steel structures?
he fire resistance of a cold-formed steel profile can be calculated according Eurocode 3, Part 1.2. In this standard, there is an informative annex, the Annex E, devoted to Class-4 cross sections, which allows to calculate the critical temperature of the class 4 profile in a way more accurate and less conservative than in the body of the document. This is very useful to calculate the fire resistance of purlins in industrial buildings. On the other hand, when the cold-formed steel profiles are protected by the sheathing –and this is the case in residential housing—the fire resistance is then determined by the sheathing material. The manufacturer normally gives information on fire resistances of the cladding.
