There are ten separate Structural Eurocodes:

• EN 1990 Eurocode: Basis of structural design
• EN 1991 Eurocode 1: Actions on structures
• EN 1992 Eurocode 2: Design of concrete structures  official source
• EN 1993 Eurocode 3: Design of steel structures
• EN 1994 Eurocode 4: Design of composite steel and concrete structures
• EN 1995 Eurocode 5: Design of timber structures
• EN 1996 Eurocode 6: Design of masonry structures
• EN 1997 Eurocode 7: Geotechnical design
• EN 1998 Eurocode 8: Design of structures for earthquake resistance
• EN 1999 Eurocode 9: Design of Aluminium Structures

Each Eurocode comprises a number of ‘Parts’, which are published as separate documents. Each Part consists of the main body of text, normative annexes, and informative annexes (the ‘relevance’ of which is decided on a national basis).

For a steel detailer, Eurocode 3 is the most relevant and helpful. As often, it is the steel detailers scope to design the joints, the green book Simple joints to Eurocode 3 is most helpful and should be adhered to.
