Full title and description

NTP RK 01-01-3.1(4.1)-2012 — НТП РК 01-01-3.1(4.1)-2012. Normative-technical guidance on loadings and actions on buildings, covering snow loads and (where applicable in a companion document) wind actions; prepared to supplement and interpret the provisions of СН РК EN 1991-1-3 and СН РК EN 1991-1-4 for application in the Republic of Kazakhstan.

Abstract

This NTP provides procedures, characteristic values, regional zonation and example calculations for determining snow loads on ground and on building roofs, and references complementary guidance for wind actions. It was prepared to adapt EN 1991 guidance to national conditions in Kazakhstan and to give practical calculation methods, form‑factors, local‑effect rules and worked examples for designers and technical specialists.

General information

• Publication date: Designation year 2012; published/issued on 29 December 2014 by the Committee for Construction Affairs (entry/announcement), with practical introduction dates referenced in related publications (introduced for application in 2015 in companion material).
• Publisher: Committee for Construction Affairs, Housing and Communal Services and Land Management (under the Ministry of National Economy of the Republic of Kazakhstan) — issued as a Republic of Kazakhstan normative‑technical guidance (НТП РК).
• ICS / categories: Construction; loads and actions on buildings; structural safety; national technical guidance (related to EN 1991 series).
• Edition / version: NTP RK 01-01-3.1(4.1)-2012 (designation year 2012; issued in the official register in late 2014).
• Number of pages: Approximately 227 pages (electronic version reported in document repositories).

Scope

The guidance covers classification of snow actions, characteristic values and zonation of snow loads on the ground across Kazakhstan, methods for determining snow load on roofing and coverings (including form coefficients for different roof geometries), rules for extraordinary snow events, local effects (drifts, edge overhangs, snow guards), worked examples and normative appendices (mandatory and informative) for practical calculation and application. It is intended as a national supplement/interpretation of EN 1991‑1‑3 (snow) and is published alongside companion material for wind actions.

Key topics and requirements

• Classification of actions and calculation situations for normal and extraordinary snow conditions.
• Characteristic values of snow load on ground and maps/zoning of Kazakhstan by snow load.
• Determination of snow load on different roof types and form‑factor coefficients (single‑sloped, double‑sloped, multi‑span, cylindrical, etc.).
• Rules for local effects: accumulations near parapets, projections, roofs adjoining higher buildings, snow guards and other obstructions.
• Combination rules, worked examples, and appendices with mandatory coefficients and informative justification of values for national use.

Typical use and users

Primary users are structural and geotechnical engineers, building designers, technical reviewers, code officials, researchers and university teachers/students working on building design in Kazakhstan who require national guidance for applying EN‑based load rules to local climate and construction practice. The guide is used for roof and structural loading checks, design of snow‑retention measures and for establishing load combinations in structural calculations.

Related standards

Directly related to and intended to complement СН РК EN 1991‑1‑3 (snow loads) and СН РК EN 1991‑1‑4 (wind actions). It is part of the NTP RK series of normative‑technical guides (loads and actions on buildings) and should be used together with other national design documents and relevant Eurocode‑based СН RK documents.

FAQ

Q: What is this standard?

A: NTP RK 01-01-3.1(4.1)-2012 is a Kazakh normative‑technical guidance document that provides national methods and values for determining snow loads (and is published alongside companion guidance for wind actions) for use in building design.

Q: What does it cover?

A: It covers characteristic snow loads on the ground and on roof coverings, regional zoning of snow loads for Kazakhstan, form‑factors for different roof geometries, local accumulation effects, extraordinary snow events, combinations and worked examples to support structural design.

Q: Who typically uses it?

A: Structural engineers, designers, project reviewers, code authorities, researchers and students working on building design and load determinations in Kazakhstan.

Q: Is it current or superseded?

A: The document was placed on the official register in late 2014 but has been withdrawn (утратил силу); PRG records the document as having been taken out of force on 20 December 2017 by a Committee order. Users should confirm the currently applicable national load guidance and any subsequent replacements or updates before relying on this NTP for new designs.

Q: Is it part of a series?

A: Yes — it is part of the NTP RK series of normative‑technical guidance for “Loadings and actions on buildings” and is linked to the СН РК EN 1991 series (separate NTPs address snow and wind aspects and related parts of EN 1991).

Q: What are the key keywords?

A: Snow load; load zonation; roof form factor; local effects; EN 1991; НТП РК; Kazakhstan building codes.
