Introduction Scope

1.1.1 Scope of Eurocode 2

P(1) Eurocode 2 applies to the design of buildings and civil engineering works in plain, reinforced and prestressed concrete. It is subdivided into various separate parts, see 1.1.2 and 1.1.3.

P(2) This Eurocode is only concerned with the requirements for resistance, serviceability and durability of structures. Other requirements, e.g. concerning thermal or sound, insulation, are not considered. P(3) Execution1 is covered to the extent that is necessary to indicate the quality of the construction materials and products which should be used and the standard of workmanship on site needed to comply with the assumptions of the design rules. Execution and workmanship are covered in Chapters 6 and 7, and are to be considered as minimum requirements which may have to be further developed for particular types of buildings or civil engineering works1) and methods of construction1-1.

P(4) Eurocode 2 does not cover the special requirements of seismic design. Provisions related to such requirements are given in Eurocode 8 "Design of Structures in Seismic Regions"2 which complements, and is consistent with, Eurocode 2.

P(5) Numerical values of the actions on buildings and civil engineering works to be taken into account in the design are not given in Eurocode 2. They are provided in the Eurocode 1 "Bases of Design and Actions on Structures"2) applicable to the various types of construction.

1.1.2 Scope of Part 1 of Eurocode 2

P(1) Part 1 of Eurocode 2 gives a general basis for the design of buildings and civil engineering works in reinforced and prestressed concrete made with normal weight aggregates (see 1.1.3 for supplementary Parts covering additional methods of construction, materials, and type of structure).

P(2) In addition, Part 1 gives detailed rules which are mainly applicable to ordinary buildings. The applicability of these rules may be limited, for practical reasons or due to simplifications; their use and any limits of applicability are explained in the text where necessary.

P(3) The following subjects are dealt with in Part 1.

— Chapter 1: Introduction;

— Chapter 3: Material Properties;

— Chapter 4: Section and Member Design;

— Chapter 5: Detailing Provisions;

— Chapter 6: Construction and Workmanship.

— Chapter 7: Quality Control.

— Appendix 1: Time-dependent Effects.

— Appendix 2: Non-linear Analysis.

— Appendix 3: Additional Design Procedures for Buckling.

— Appendix 4: Checking deflections by calculation.

P(4) Chapters 1 and 2 are common to all Eurocodes, with the exception of some additional clauses which are required for concrete.

P(5) This Part 1 does not cover:

— particular aspects of special types of building (such as tall buildings);

— particular aspects of special types of civil engineering works (such as viaducts, bridges, dams, pressure vessels, offshore platforms or liquid-retaining structures);

— no-fines concrete and aerated concrete components, and those made with heavy aggregate or containing structural steel sections (see Eurocode 4 for composite steel-concrete structures).

2) At present at the draft stage.

1.1.3 Further Parts of Eurocode 2

P(1) This Part 1 of Eurocode 2 will be supplemented by further Parts which will complement or adapt it for particular aspects of special types of building or civil engineering works, special methods of construction and certain other aspects of design which are of general practical importance.

P(2) Further Parts of Eurocode 2 which, at present, are being prepared or are planned, include the following (listed in 2 distinct categories):

— Part 1A: Plain or lightly reinforced concrete structures;

— Part 1B: Precast concrete structures;

— Part 1C: The use of lightweight aggregate concrete;

— Part 1D: The use of unbonded and external prestressing tendons;

— Part 1E: Design for fatigue of concrete structures;

— Part 10: Fire resistance of concrete structures;

— Part 2: Reinforced and Prestressed Concrete Bridges;

— Part 3: Concrete Foundations and Piling;

— Part 4: Liquid-retaining Structures;

— Part 5: Temporary Structures. Structures having a Short Design Life;

— Part 6: Massive Civil Engineering Structures.

1.2 Distinction between Principles and Application Rules

P(1) Depending on the character of the individual clauses, distinction is made in this eurocode between Principles and Application Rules.

P(2) The Principles comprise:

— general statements and definitions for which there is no alternative, as well as

— requirements and analytical models for which no alternative is permitted unless specifically stated. P(3) In this code the Principles are preceded by the letter P.

P(4) The Application Rules are generally recognized rules which follow the Principles and satisfy their requirements.

P(5) It is permissible to use alternative design rules different from the Application Rules given in the Eurocode, provided that it is shown that the alternative rules accord with the relevant Principles and are at least equivalent with regard to the resistance, serviceability and durability achieved for the structure with the present Eurocode.

P(6) In this code Application Rules are off-set to the right.

1.3 Assumptions

P(1) The following assumptions apply:

— Structures are designed by appropriately qualified and experienced personnel.

— Adequate supervision and quality control is provided in factories, in plants, and on site.

— Construction is carried out by personnel having the appropriate skill and experience.

— The construction materials and products are used as specified in this Eurocode or in the relevant material or product specifications.

— The structure will be adequately maintained.

— The structure will be used in accordance with the design brief.

P(2) The design procedures are valid only when the requirements for execution and workmanship given in Chapters 6 and 7 are also complied with.

P(3) Numerical values identified by |_| are given as indications. Other values may be specified by Member

States.
