CEN/TC 250/SC 4 - Eurocode 4: Design of composite steel and concrete structures

Supplementary to Part 1-1. Additional and varied rules to be used for the design of composite structures which are required to avoid premature structural collapse and to limit the spread of fire in the accidental situation of exposure to fire.

(1) Part 2 of Eurocode 4 gives design rules for steel-concrete composite bridges or members of bridges, additional to the general rules in EN 1994-1-1. Cable stayed bridges are not fully covered by this part.
(2) The following subjects are dealt with in Part 2:
Section 1:   General
Section 2:   Basis of design
Section 3:   Materials
Section 4:   Durability
Section 5:   Structural analysis
Section 6:   Ultimate limit states
Section 7:   Serviceability limit states
Section 8:   Decks with precast concrete slabs
Section 9:   Composite plates in bridges
(3) Provisions for shear connectors are given only for welded headed studs.
NOTE: Reference to guidance for other types as shear connectors may be given in the National Annex.

Supplementary to Part 1-1. Additional and varied rules to be used for the design of composite structures which are required to avoid premature structural collapse and to limit the spread of fire in the accidental situation of exposure to fire.

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.

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.

ENV 1994-2:1997 gives a general basis for the design of composite bridges. In addition, ENV 1994-2:1997 gives a specific basis for the design of composite structures and members for bridges such as road, railway, and pedestrian bridges, and detailed rules for composite bridge structures such as beam and slab bridge decks, box girders, trusses and columns that support bridge decks.
