Hot-dip galvanized steel is characterized by slower heating behavior in the event of fire. Hot-dip galvanizing can therefore often achieve a fire resistance period of 30 minutes (R30) without additional fire protection measures. However, expert knowledge is required to apply fire protection through hot-dip galvanizing in practice, as a so-called "hot design" must be carried out. To simplify matters, mb AEC Software is the first construction software manufacturer to integrate hot-dip galvanizing as a new fire protection option in a structural analysis module.
With the new module S855.de "Steel cross-sections, verifications in case of fire - EC 3, DIN EN 1993-1-2", hot-dip galvanized steel profiles can be verified with regard to their load-bearing capacity under fire load. "No "extensive expert knowledge" of hot design is required to use the structural analysis module S855.de. The necessary entries can be made by any structural engineer," emphasizes Uli Höhn, Managing Partner of mb AEC Software and adds: "However, this is not intended to be a plea for a "blind" application of the software." To prevent this, the software manufacturer and the Hot Dip Galvanizing Institute offer a wealth of information on the technical and normative principles of fire protection through hot dip galvanizing and on the subject of hot design.
Verifiable proof of load-bearing capacity under fire exposure
After appropriate data input, the software provides a complete and verifiable output of the proof of load-bearing capacity under fire exposure. This includes all relevant information for the inspector as well as the option to output intermediate results for better traceability. In addition to fire protection by hot-dip galvanizing, the new structural analysis module also assesses unprotected ("black") steels and fire protection materials such as cladding and sprayed plaster. This ensures direct comparability between the various fire protection solutions. Incidentally, the new S855.de module can also be used by engineering firms that have not previously worked with mb software.
