In total there are 58 EN Eurocode parts distributed in the ten Eurocodes (EN 1990 – 1999). All of the EN Eurocodes relating to materials have a Part 1-1 which covers the design of buildings and other civil engineering structures and a Part 1-2 for fire design. The codes for concrete, steel, composite steel and concrete, and timber structures and earthquake resistance have a Part 2 covering design of bridges. These Parts 2 should be used in combination with the appropriate general Parts (Parts 1).
