Full title and description

NTP RK 01-01-3.1(4.1)-2017 — "Loads and actions on buildings. Part 1-3. Snow loads (to SP RK EN 1991-1-3:2003/2011). Part 1-4. Wind actions (to SP RK EN 1991-1-4:2003/2011)". This normative-technical publication adapts the relevant parts of Eurocode (EN 1991‑1‑3 and EN 1991‑1‑4) for use in the Republic of Kazakhstan, providing national maps, coefficients and application rules for snow and wind loading on structures.

Abstract

This document specifies national regulations and guidance for determination of snow loads and wind actions on buildings and structures in Kazakhstan. It harmonizes Eurocode procedures with Kazakhstan‑specific parameters (regional snow/wind zones, terrain/exposure categories, combination rules and local modification factors) so designers can apply EN‑based methods in compliance with national practice.

General information

• Status: Active (document in force / used as a national normative‑technical document in Kazakhstan).
• Publication date: 2017 (designation includes the year 2017; later technical updates and adaptations have been noted in national practice).
• Publisher: Republic of Kazakhstan — issued as a national normative‑technical document and published/distributed through official Kazakhstani standards/technical document channels and commercial standards aggregators.
• ICS / categories: Construction (actions on structures); structural loading — snow loads and wind actions; adaptation of Eurocode EN 1991 parts.
• Edition / version: NTP RK 01-01-3.1(4.1)-2017 (first published 2017; national updates/modifications referenced in later updates of related SP documents).
• Number of pages: Approximately 128 pages (commercial listings and document catalogues list a 128‑page electronic edition).

Scope

The standard covers principles, calculation procedures, parameters and national coefficients needed to determine characteristic and design values of snow loads (Part 1‑3) and wind actions (Part 1‑4) on buildings and structures across Kazakhstan. It applies to the structural design process where EN‑based load models are used and where national values (zones, coefficients, combinations) must be applied for compliance with Kazakh regulatory practice.

Key topics and requirements

• Definition of snow load zones, characteristic snow load on the ground and rules for transforming ground snow load to roof loads (roof shape, thermal effects, accumulation, drifting).
• Wind loading: basic wind speed maps, terrain/roughness/exposure categories, gust and mean wind considerations, pressure coefficients for building surfaces and load application rules.
• National modification factors and rules for applying EN 1991‑1‑3 and EN 1991‑1‑4 procedures within Kazakh practice.
• Load combination guidance (snow, wind, self‑weight, imposed loads) and climatic considerations for reliability in the national context.
• Worked examples, tables and maps to assist designers in selecting appropriate coefficients and regional values.

Typical use and users

Structural engineers, building designers, code compliance reviewers, geotechnical and wind‑climate specialists, software developers of structural analysis packages, and construction authorities in Kazakhstan use this document to determine design snow and wind loads consistent with national requirements and Eurocode‑based methods. The standard is commonly referenced in design offices and in engineering modules of CAD/FEA software for Kazakhstan projects.

Related standards

Primary related documents include SP RK EN 1991‑1‑3 (snow loads) and SP RK EN 1991‑1‑4 (wind actions) (the NTP adapts these parts for national application). Other related Kazakh rules on climatology and construction practice (for example, national climatology and building climate rules) are used together with this NTP.

FAQ

Q: What is this standard?

A: NTP RK 01-01-3.1(4.1)-2017 is a Kazakh normative‑technical document that provides national rules and parameters for calculating snow loads (Part 1‑3) and wind actions (Part 1‑4) on buildings, aligning EN 1991 procedures with Kazakhstan‑specific values and practices.

Q: What does it cover?

A: It covers regional snow and wind maps, terrain and exposure classifications, coefficients and formulas to derive characteristic and design loads on roofs and structural elements, guidance on load combination and application of EN‑based methods in Kazakhstan.

Q: Who typically uses it?

A: Structural and civil engineers, designers and compliance authorities in Kazakhstan, plus software developers and consulting firms working on Kazakhstan projects, use this document when determining wind and snow loads for design and verification.

Q: Is it current or superseded?

A: The document is listed as active in commercial and standards catalogues (published 2017). National practice may reference updates or related SP documents; users should verify whether any amendments or newer editions have been issued by Kazakh regulatory bodies before applying the rules.

Q: Is it part of a series?

A: Yes — it forms part of the NTP RK series of normative‑technical publications and specifically aligns with the SP RK EN 1991 series (Actions on structures / Eurocode 1) as the national adaptation for snow and wind parts. Designers commonly use it alongside other NTP RK and SP RK documents for complete design rules.

Q: What are the key keywords?

A: Snow load, wind load, EN 1991, Kazakhstan, NTP RK, load combinations, terrain/exposure, roof accumulation, wind pressure coefficients.
