CEN/TC 250/SC 1/WG 4 - Actions on structures exposed to fire

1.1   Scope of EN 1991 1 2
(1)   The methods given in this Eurocode are applicable to buildings and civil engineering works, with a fire load related to the building and its occupancy.
(2)   EN 1991 1 2 deals with thermal and mechanical actions on structures exposed to fire. It is intended to be used in conjunction with the fire design Parts of EN 1992 to EN 1996 and EN 1999 which give rules for designing structures for fire resistance.
(3)   EN 1991 1 2 contains thermal actions either nominal or physically based. More data and models for physically based thermal actions are given in annexes.
(4)   EN 1991 1 2 does not cover the assessment of the damage of a structure after a fire.
(5)   EN 1991 1 2 does not cover supplementary requirements concerning, for example:
-   the possible installation and maintenance of sprinkler systems;
-   conditions on occupancy of building or fire compartment;
-   the use of approved insulation and coating materials, including their maintenance.
1.2   Assumptions
(1)   In addition to the general assumptions of EN 1990 the following assumptions apply:
-   any active and passive fire protection systems taken into account in the design will be adequately maintained;
-   the choice of the relevant design fire scenario is made by appropriate qualified and experienced personnel, or is given by the relevant national regulation.
