Question:
How are hot-dip galvanized components considered for fire resistance in the RF‑/STEEL EC3 add-on module?
Answer:
Hot-dip galvanized components can be considered as follows:
Since the emissivity increases abruptly, then remains constant, and is only included as a factor in the Eurocode formulas, you could calculate and use the emissivity for a component with the fire resistance class > 30 by hand in this case. (mean value).
This value takes into account the reduction at the start of the fire.
