Fire design on elevated temperature
Consteel performs cross section resistance and buckling checks for all steel members which are subjected to fire effect by using the adequate formulas from the EuroCode 3 standard.
Classification of cross-section (EN 1993-1-2 4.2.2)
Cross-sections are classified as for normal tempereature (EN 1993-1-1) but using the reduced value for ε.
