EN 1992-1-1:2004 Eurocode 2 – Design of concrete structures. General rules and rules for buildings
Part 1-2 of EN 1992 deals with the design of concrete structures for the accidental situation of fire exposure. It only identifies differences from, or supplements to, normal temperature design and deals only with passive methods of fire protection. Active methods are not covered. Rthe Eurocode applies to concrete structures that are required to fulfil certain functions when exposed to fire, in terms of avoiding premature collapse of the structure (load bearing function); limiting fire spread (flame, hot gases, excessive heat) beyond designated areas (separating function). It also gives principles and application rules for designing structures for specified requirements in respect of the aforementioned functions and the levels of performance. It applies to structures, or parts of structures, that are within the scope of EN 1992-1-1 and are designed accordingly. The methods given in this Part 1-2 of EN 1992 are applicable to normal weight concrete up to strength class C90/105 and for lightweight concrete up to strength class LC55/60.
