In theEurocode series ofEuropean standards (EN) related toconstruction,Eurocode 4: Design of composite steel and concrete structures (abbreviatedEN 1994 or, informally,EC 4) describes how to design ofcompositestructures, using thelimit state design philosophy. It was approved by theEuropean Committee for Standardization (CEN) on 4 November 2004. Eurocode 4 is divided in two parts EN 1994-1 and EN 1994-2.
Eurocode 4 is intended to be used in conjunction with:
EN 1994-1-1 gives a general basis for the design of composite structures together with specific rules forbuildings.
EN 1994-1-2 deals with the design of composite steel and concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1994-1-1 andEN 1991-1-2. This part only identifies differences from, or supplements to, normal temperature design and deals only with passive methods of fire protection. Active methods are not covered.
EN 1994-2 gives design rules for steel-concrete compositebridges or members of bridges, additional to the general rules in EN 1994-1-1. Cable stayed bridges are not fully covered by this part.
