EN 1990 'Eurocode: Basis of structural design' is the head document in the Eurocode suite. It describes the basis and general principles for the structural design and verification of buildings and civil engineering works including geotechnical aspects, the principles and requirements for safety and serviceability of structures and guidelines for related aspects of structural reliability in all circumstances in which a structure is required to give adequate performance, including fire and seismic events. Consisting of only one part, it is used with all the other Eurocodes (1 to 9) for design. A revised national annex, amended with Annex A2 for bridges, is due out in February 2009.
