CEN/TC 250/SC 4/WG 4 - Evolution of EN 1994-1-1, EN 1994-1-2 and EN 1994-2

1.1   Scope of EN 1994-1-1
(1) EN 1994-1-1 gives general rules for the design of steel and concrete composite structures and supplementary provisions specific for buildings.
NOTE   Specific rules for bridges are given in EN 1994-2.
1.2   Assumptions
(1) The assumptions of EN 1990 apply to EN 1994-1-1.
(2) In addition to the general assumptions of EN 1990, the assumptions given in EN 1992–1–1, EN 1992-1-2, and EN 1993-1-1 apply to this document.
(3) EN 1994-1-1 is intended to be used in conjunction with EN 1990, EN 1991 (all parts), EN 1992-1-1, EN 1993 (all parts), EN 1997 (all parts), EN 1998 (all parts when steel and concrete composite structures are built in seismic regions), EN 1090-1, EN 1090-2, EN 1090-4, EN 13670 and ENs for construction products relevant to steel and concrete composite structures.

(1) EN 1994-1-2 gives rules for the design of steel-concrete composite structures for the accidental design situation of fire exposure. It only identifies differences from, or supplements to, rules for normal temperature design.
(2) EN 1994-1-2 only applies to structures, or parts of structures, that are within the scope of EN1994-1-1 and are designed accordingly.

EN 1994-2 gives design rules for steel-concrete composite bridges or members of bridges, supplementary to the general rules given in EN 1994-1-1.
