BS EN 1990:2002 pdf download.Eurocodes – Basis of Structural Design.
(1) EN 1990 establishes Principles and requirements for the safety, serviceability and
durability of structures, describes the basis for their design and verification and gives guidelines for related aspects of structural reliability.
(2) EN 1990 is intended to be used in conjunction with EN 1991 to EN 1999 for the
structural design of buildings and civil engineering works, including geotechnical aspects, structural fire design, situations involving earthquakes, execution and temporary structures.
NOTE For the design of special construction works (e.g. nuclear installations, darns. etc.), other provisions than those in EN 1990 to EN 1999 might be necessary.
(3) EN 1990 is applicable for the design of structures where other materials or other
actions outside the scope of EN 1991 to EN 1999 are involved.
(4) EN 1990 is applicable for the structural appraisal of existing construction, in developing the design of repairs and alterations or in assessing changes of use.
NOTE Additional or amended provisions might be necessary where appropriate.
1.3 Assumptions
(1) Design which employs the Principles and Application Rules is deemed to meet the requirements provided the assumptions given in EN 1990 to EN 1999 are satisfied (see Section 2).
(2) The general assumptions of EN 1990 are:
— the choice of the structural system and the design of the structure is made by appropriately qualified and experienced personnel;
— execution is carried out by personnel having the appropriate skill and experience:
— adequate supervision and quality control is provided during execution of the work, i.e. in design offices, factories, plants, and on site;
— the construction materials and products are used as specified in EN 1990 or in EN 1991 to EN 1999 or in the relevant execution standards, or reference material or product specifications;
— the structure will be adequately maintained:
the structure will be used in accordance with the design assumptions.
