SIST EN 1992-2:2005 is the Slovenian adoption of EN 1992-2:2005 from CEN. It gives the Eurocode 2 rules for designing and detailing road, rail and footbridges in plain, reinforced and prestressed concrete, and it is written for designers, constructors, clients, quality managers and authorities.
What does SIST EN 1992-2:2005 specify?
SIST EN 1992-2:2005 specifies bridge-specific design and detailing rules that complement EN 1992-1-1. It applies to bridges and parts of bridges made with normal and lightweight aggregates, and it organizes the subject from general design through execution stages.
The document is structured into Sections 1 to 12 and Section 113, followed by Annexes A to QQ. In practice, that means it covers the whole bridge design chain: basis of design, materials, durability, analysis, ultimate and serviceability limit states, detailing, precast work, lightweight aggregate concrete, plain and lightly reinforced concrete, and execution-stage design.

What are the key requirements of SIST EN 1992-2:2005?
Design basis, actions and national choices
SIST EN 1992-2:2005 is based on the limit state concept with partial factors, and it treats EN 1992-1-1 as the general base document for bridges. Clause 5.1.3 requires critical load cases and combinations to be checked so that the worst design condition is found in every relevant part of the structure.
A large number of clauses are left to National Annex choice. For a bridge project, that matters because the country-specific values control concrete classes, material factors, cover rules, redistribution limits, crack control limits and several detailing values.
Materials, durability and cover
SIST EN 1992-2:2005 sets bridge-oriented rules for concrete strength, reinforcing steel ductility and design strengths. Clause 3.1.6 defines the design compressive and tensile strengths, while 3.2.4 requires reinforcement ductility suited to bridge use.
Durability is treated as a bridge exposure issue, not just a material issue. Clause 4.2 requires the designer to consider water penetration, leakage from the carriageway, de-icing salts, waterproofing and abrasion, and Clause 4.4.1.2 adds special cover rules for interfaces with existing concrete and for bare road bridge decks.
Structural analysis and ULS
Clause 5 allows recognised time-dependent analysis methods for bridges, and Annex KK expands the treatment of creep, shrinkage and redistribution. Clause 5.2 gives bridge-specific imperfection rules, including an inclination model for members in compression, which matters because bridge geometry and execution tolerances influence stability.
At ULS, the standard covers bending, shear, torsion, partially loaded areas, fatigue and membrane elements. The shear rules in 6.2 distinguish members with and without design shear reinforcement, and Clauses 6.2.4 to 6.2.106 address web-to-flange shear, joints cast at different times, and shear-transverse bending interaction.
SLS, detailing and execution
For serviceability, Clause 7 covers stress limits, crack control and deflection control. Crack width limits depend on exposure class, and Clause 7.3.2 requires minimum reinforcement in tensile zones, including special treatment of flanged sections and shrinkage reinforcement.
Detailing clauses cover bundled bars, prestressing tendons, anchorage zones, couplers, beams, columns, deep beams, pile caps and lightweight aggregate concrete. Section 113 then requires the design to take construction stages into account whenever erection sequence, staged loading or rheological redistribution can affect stability, forces or geometry.
What terms does SIST EN 1992-2:2005 define?
- ULS means ultimate limit state, the safety check against collapse or loss of resistance.
- SLS means serviceability limit state, the check for stress, cracking, deformation and usability.
- LWAC means lightweight aggregate concrete, which has its own detailing rule for bar size and bundling.
- HSC means high strength concrete, for which Annex B gives a separate creep and shrinkage model.
- SFC means silica-fume concrete, which Annex B treats separately in delayed strain calculations.
- fcd is the design value of concrete compressive strength, used in resistance checks.
- fctd is the design value of concrete tensile strength, used for cracking and reinforcement checks.
Who uses SIST EN 1992-2:2005?
SIST EN 1992-2:2005 is used by bridge designers, structural engineers, contractors, checking engineers, clients and relevant authorities. It is also used by committees writing related structural, product, testing and execution standards. In practice, they use it to size bridge members, choose reinforcement and prestressing, check durability, define execution stages and set national parameters.
What changed in SIST EN 1992-2:2005 from the previous edition?
SIST EN 1992-2:2005 supersedes ENV 1992-2:1996. The foreword states that it is the European Standard version of Eurocode 2, with bridge-specific clauses added or modified relative to EN 1992-1-1.
Which standards are used with SIST EN 1992-2:2005?
- EN 1992-1-1 - provides the general Eurocode 2 rules that apply unless EN 1992-2 changes them.
- EN 1990 - provides the basis for load combinations, including Annex A2.
- EN 1991-2 - provides traffic actions and the dynamic factor referenced in the symbols.
- EN 1991-1-6 - provides actions during execution.
- EN 13670 - provides execution-related deviation classes referenced for geometric imperfections.
- EN 1997 - is named as a companion Eurocode for new structures.
- EN 1998 - is named as a companion Eurocode for new structures.
What does the SIST EN 1992-2:2005 document contain?
The document contains symbols, bridge-specific clauses and numerous formulas for design values, resistance checks and serviceability checks. It includes methods for shear, torsion, fatigue, prestressed members, crack control, and time-dependent effects such as creep and shrinkage.
It also contains annex methods for special cases, including membrane elements, shell elements, soil-structure interaction, non-linear analysis safety format, and typical bridge discontinuity regions. Several figures and equations support detailing and verification, such as crack control, shear models, anchorage zones and execution-stage effects.
