SHNK 2.05.03-12 PDF

Full title and description

SHNK 2.05.03-12 — "Мосты и трубы" (English: "Bridges and pipes"). This is a national set of design rules and norms addressing the planning, design and basic technical requirements for bridges, culverts and pipes used on road and railway networks.

Abstract

SHNK 2.05.03-12 provides prescriptive and performance-oriented requirements for the design, structural calculation, hydraulic consideration and basic arrangement of permanent bridges, viaducts, overpasses and pipes/culverts under embankments. The document sets load models, material and construction provisions, and rules for basic geotechnical and foundation solutions applicable to road and railway infrastructure.

Scope

Applies to the design and reconstruction of permanent bridges, overpasses, viaducts and pipes (culverts) beneath embankments for road and railway networks, including traffic and hydraulic provisions, structural systems, foundations, and basic durability and safety requirements. The scope typically covers new construction and major reconstruction projects on national, regional and local roads and railways.

Key topics and requirements

• Design load models and combinations for road and railway traffic, dynamic coefficients and impact factors.
• Structural design rules for superstructure and substructure elements (girders, decks, piers, abutments, bearings).
• Hydraulic and scour considerations for watercourse crossings; sizing and arrangement of culverts and pipes under embankments.
• Foundation and geotechnical requirements for bridge supports and embankment/pipeline interaction.
• Material specifications, durability requirements and protective measures for concrete and steel elements.
• Basic rules for inspection, load-rating and maintenance planning; assessment procedures for existing structures (load capacity evaluations, repairs and strengthening measures).
• Requirements for traffic safety elements, clearances, pedestrian provisions and coordination with roadway geometry.

Typical use and users

Used by bridge and highway design institutes, structural and geotechnical engineers, contractors, inspection and maintenance teams, and public authorities responsible for road and railway infrastructure. The standard is referenced in project documentation, engineering calculations, permitting and state expertise for bridge and culvert projects.

Related standards

Closely related to other national and regional bridge/road design rules and older СНиП/SP editions (for example СНиП/СП series on "Bridges and pipes" and consolidated rules). The later consolidated update is SHNK 2.05.03-22; other referenced documents in practice include KMK and technical instructions for inspection and load-rating of bridges.
