Fire detail
The style of fire exposition and fire protection can be defined in this window. There are two types of unprotected detail: cross-section exposed from all four sides or only from three sides (mainly for beams). The identical options are available for protected cross-sections. Columns in wall (protected on two opposite sides) can be exposed from one or two sides.
The cross-sections can be protected by fire protective claddings. The fire protection delays the start of charring tch and changes the charring rate. The timber, wood-based panels, plasterboards and mineral wood can be used as a fire protective material. The necessary properties like density, thickness and ply number have to be specified for any material. The gaps properties have to be specified for plasterboards additionally. The fasteners length have to be specified for mechanically connected claddings, as influences the failure time of protection tf. Other protective material with user defined characteristics can be also entered for the detail. These characteristics are described in the chapter "Calculation of char layer".
