28/05/2020 – Ver. 79 – Fire protections added to the fire module and Egoin panels added to CLT archives
In the latest version of the software we added new features:
- Fire protections: checks on the load-bearing function of structural members initially protected from exposure to fire can now be performed. Gypsum Plasterboard, Gypsum Plasterboard Type F, Gypsum Fibreboard and custom definitions can be used. In the first three cases, the software automatically calculates the time of start of charring tch, the failure time of protection tf (evaluated differently for vertical and horizontal elements), the time ta and the insulation coefficient k2. In the case of custom definition, the designer can manually enter the parameters in order to manage protection solutions not listed in the standard or defining specifications of a particular manufacturer. For all protected structural elements, the rules proposed in EN 1995-1-2 are used with all the cases proposed by the standard for the calculation of the charring depth dchar,n, the calculation of k0 and k2 and the calculation of the effective charring depth deff.
The joist floors and the framed walls with protections are calculated as assemblies with void cavities following the indications of Annex D of Eurocode EN 1995-1-2, which provides for different times of start of charring for the sides directly exposed to fire and for the sides facing the empty cavities.
- CLT panels by the Spanish manufacturer Egoin added: it is now possible to check the CLT structures made with Egoin panels
