|ICS Code (Technical aspects):||91.010.30|
Scope of Eurocode 2
(1)P Eurocode 2 applies to the design of buildings and civil engineering works in concrete. It complies with the principles and requirements for the safety and serviceability of structures, the basis of their design and verification that are given in EN 1990 - Basis of structural design.
(2)P Eurocode 2 is only concerned with requirements for resistance, serviceability, durability and fire resistance concrete structures. Other requirements, e.g. concerning thermal or sound insulation, are not considered.
(3)P Eurocode 2 is intended to be used in conjunction with:
- EN 1990 "Basis of structural design"
- EN 1991 "Actions on structures"
- hEN´s for construction products relevant for concrete structures
- ENV 13670-1 "Execution of concrete structures . Part 1: Common rules"
- EN 1998 "Design of structures for earthquake resistance", when concrete structures are built in seismic regions
(4)P Eurocode 2 is subdivided in various parts:
- Part 1-1: General rules and rules for buildings
- Part 1-2: General rules - Structural fire design
- Part 2: Concrete bridges
- Part 3: Liquid retaining and containment structures
Scope of Part 1-2 of Eurocode 2
(1)P This Part 1-2 of EN 1992 deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1992-1-1 and EN 1991-1-2. This part 1-2 only identifies differences from, or supplements to, normal temperature design.
(2)P This Part 1-2 of EN 1992 deals only with passive methods of fire protection. Active methods are not covered.
(3)P This Part 1-2 of EN 1992 a pplies 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)
(4)P This Part 1-2 of EN 1992 gives principles and application rules (see EN 1991-1-2) for designing structures for specified requirements in respect of the aforementioned functions and the levels of performance.
(5)P This Part 1-2 of EN 1992 applies to structures, or parts of structures, that are within the scope of EN 1992-1-1 and are designed accordingly. However, it does not cover:
- structures with prestressing by external tendons
- shell structures
(6)P 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. Additional and alternative rules for strength classes above C50/60 are given in section 6.
