SHNK 2.03.05-13 PDF

Full title and description

SHNK 2.03.05-13 — "Steel structures. Design standards" (Рус.: "Стальные конструкции. Нормы проектирования"). National technical norms for the design, calculation and detailing of steel building structures used in the Republic of Uzbekistan.

Abstract

This document establishes design rules, material requirements, calculation methods and detailing principles for steel structures of buildings and general-purpose engineering structures. Topics include steel grades and material properties, limit states and load combinations, member strength and stability (including buckling), welded and bolted connections, fabrication and tolerances, corrosion protection and special provisions for structures under unusual operating conditions.

General information

• Status: Replaced by SHNK 2.03.05-23 (the 2013 text is superseded by the later 2023 edition).
• Publication date: Approved by order №42 on 9 April 2013; came into force 1 May 2013 (official Tashkent edition, 2013).
• Publisher: State Committee of the Republic of Uzbekistan for Architecture and Construction (Gosarkhitektstroy).
• ICS / categories: Structures of buildings — Steel structures (ICS 91.080.13).
• Edition / version: SHNK 2.03.05-13 (2013 edition).
• Number of pages: ~148 pages (electronic/PDF editions offered by document resellers list 148 pages).

Scope

Applies to the design of steel structures for buildings and many types of engineering structures on the territory of the Republic of Uzbekistan. The standard excludes certain categories (for example, railway and highway bridges, hydraulic and reclamation structures, some pipeline systems and specialized industrial mechanisms) and includes additional requirements for structures operating in special conditions (high temperature, radiation, aggressive media, high seismicity, very large or special-span structures).

Key topics and requirements

• General design principles and limit-state approach for steel structures.
• Permitted steel grades, material properties and required certification of materials.
• Load types and combinations (permanent, variable, environmental and accidental actions) and design factors.
• Strength and stability checks for members (axial, bending, shear, combined) including buckling and lateral–torsional stability.
• Design of welded, bolted and riveted connections; detailing rules and minimum weld/bolt sizes.
• Fatigue and dynamic considerations for cyclically loaded elements.
• Fabrication, tolerances, assembly and erection rules, plus corrosion protection and coatings.
• Special provisions for unique structures (large spans, tall towers, high-temperature service, seismic regions).

Typical use and users

Used by structural and civil engineers, design offices, checking authorities, fabricators and contractors working on steel buildings and industrial structures in Uzbekistan and by international consultants requiring the Uzbek national design rules. It is also referenced by structural analysis and design software for local code checks.

Related standards

SHNK 2.03.05-13 replaced earlier national documents (for example KMK 2.03.05-97) and itself has been updated and replaced by SHNK 2.03.05-23. The standard is usually considered alongside other regional and international documents cited in its normative references (SNiP/SN/СП rules, national material standards and often cross-referenced with relevant Eurocode/EN or neighbouring countries’ documents in practice).

FAQ

Q: What is this standard?

A: A national Uzbek design standard titled "Steel structures. Design standards" (SHNK 2.03.05-13) that sets requirements for the design and detailing of steel building structures.

Q: What does it cover?

A: It covers material requirements, calculation procedures for strength and stability, connection design (welded and bolted), fabrication and erection tolerances, corrosion protection and special rules for structures in unusual operating conditions.

Q: Who typically uses it?

A: Structural engineers, design organizations, fabricators, contractors and regulatory/checking bodies responsible for steel buildings and general-purpose steel structures in Uzbekistan (and international consultants working on Uzbek projects).

Q: Is it current or superseded?

A: The SHNK 2.03.05-13 (2013) text has been superseded — current national practice references the later consolidated edition SHNK 2.03.05-23 (the 2013 edition is therefore treated as replaced). For projects you should check whether the newer SHNK 2.03.05-23 or other amendments apply.

Q: Is it part of a series?

A: Yes — it is part of a family of Uzbek construction norms (SHNK / KMK / КМК series) covering different materials and structural systems; related documents address aluminum, timber, concrete and thin‑walled steel systems.

Q: What are the key keywords?

A: Steel structures, design rules, material properties, buckling, welded connections, bolted connections, fabrication, corrosion protection, Uzbek construction norms (SHNK).
