What this standard covers

EN 1992 (Eurocode 2 - Design of concrete structures) is the European standard for the design of plain, reinforced and prestressed concrete. It covers the design of members at ultimate and serviceability limit states, together with detailing, durability and fire.

EN 1992-1-1 is the general part used for buildings: material properties for concrete and reinforcement, bending and axial force, shear, punching, torsion, buckling of slender members, serviceability checks on cracking and deflection, and the detailing rules for anchorage, laps and member reinforcement. EN 1992-1-2 covers structural fire design, EN 1992-2 bridges, EN 1992-3 liquid-retaining structures and EN 1992-4 fastenings for use in concrete.

Durability is handled through exposure classes: the environment a member sits in determines the concrete class and the cover to reinforcement, and those choices feed back into the structural design. Concrete strength classes follow EN 206, so a design to EN 1992 uses the C classes rather than a national classification.

What you will find in it

Concrete strength classes
The C classes of EN 206 and the strength and deformation properties derived from them, including tensile strength, modulus and creep.
Reinforcement properties
Characteristic yield strength and ductility class of reinforcing steel, and the design stress-strain relations permitted for it.
Bending and axial force
Design of sections for bending and for combined axial force and bending, using the rectangular or parabolic-rectangular stress block.
Shear and punching
Resistance of members with and without shear reinforcement, and punching shear around columns and concentrated loads on slabs.
Cracking and deflection
Serviceability checks on crack width and on deflection, with the span-to-depth approach available as a simplified route.
Durability and cover
Exposure classes and the minimum cover and concrete quality that follow, which frequently govern the section before strength does.
Detailing
Anchorage and lap lengths, minimum and maximum reinforcement, bar spacing, and the member detailing rules for beams, slabs, columns and walls.
Strut-and-tie
The design of regions where plane sections do not remain plane - deep beams, corbels, pile caps and openings - by an equilibrium truss model.

When to use this standard

Use EN 1992 for concrete design under the Eurocodes - beams, slabs, columns, walls, foundations, and fastenings into concrete through EN 1992-4. Loads come from EN 1991 and are combined by EN 1990. In Vietnam the corresponding national standard is TCVN 5574, which is used instead of, not alongside, this one.

How it fits with the other standards

Loads come from EN 1991 and are combined by EN 1990. Composite steel-concrete members are designed to EN 1994; foundations use EN 1997 for the ground and EN 1992 for the concrete; seismic design adds EN 1998. Fastenings into concrete are covered by EN 1992-4.

What each part covers

EN 1992-1-1
The general part for buildings: material properties, bending and axial force, shear, punching, torsion, buckling, serviceability, durability and detailing. The part used on almost every concrete structure.
EN 1992-1-2
Structural fire design. The reduction of concrete and reinforcement properties with temperature, tabulated data for common members, and the calculation methods for fire resistance.
EN 1992-2
Concrete bridges. Applies the general rules to bridges, with additional requirements for fatigue, prestressing and the durability of exposed structures.
EN 1992-3
Liquid-retaining and containment structures. Tanks and reservoirs, where tightness governs: crack width limits are stricter than in ordinary buildings because leakage, not strength, is the controlling criterion.
