SP 20.13330.2016 PDF

Full title and description

SP 20.13330.2016 — Свод правил "Нагрузки и воздействия" (English: "Loads and actions"). This regulatory set defines the principles for assigning loads, actions and their combinations that must be considered when performing structural calculations of buildings and civil engineering structures with respect to limit states of the first and second groups.

Abstract

This document is the updated edition of the national rules for loads and actions used in structural design. It replaces earlier editions of the corresponding SNIP/SP documents and consolidates rules for permanent, long‑term, short‑term and special loads (including wind, snow, temperature, settlement and impact effects), together with prescribed combination rules and safety factors used for ultimate and serviceability limit‑state calculations. The standard is intended to ensure uniform assignment of actions for reliable structural design across the Russian Federation.

Scope

SP 20.13330.2016 establishes requirements for the assignment of loads, actions and their combinations to be considered when calculating buildings and structures for both ultimate (limit state of the first group) and serviceability (limit state of the second group) conditions. The scope covers classification of loads (permanent, long‑term, short‑term, special), rules for determining imposed (live) loads, snow and wind actions, temperature and settlement effects, accidental loads, and combination rules in accordance with GOST 27751 and related regulatory provisions.

Key topics and requirements

• Classification and designation of loads and actions (permanent, long‑term, short‑term, variable, special, accidental).
• Rules and numerical values for imposed (live) loads on floors, roofs and stairs; load distribution assumptions for design calculations.
• Snow load determination (including regional coefficients, roof geometry factors and snow drift considerations).
• Wind load rules and coefficients, including reference wind speeds and pressure coefficients for different terrain categories.
• Temperature, settlement and soil‑structure interaction effects; differential actions and long‑term deformations.
• Combination rules for ultimate and serviceability limit states, with recommended load factors and combination coefficients.
• Special and accidental actions (impact, crane loads, explosions, concentrated loads) and guidance for their inclusion in design models.
• Tables, formulae and normative annexes to support consistent application in structural calculations and software.

Typical use and users

Primary users are structural and civil engineers, building designers, calculation specialists, code compliance officers, and developers of structural analysis/design software. The standard is used when preparing structural design calculations, specifying loads in project documentation, and verifying conformity with national regulatory requirements in Russia. It is also used in education and research as the reference for action models in structural reliability studies.

Related standards

Key related documents include GOST 27751 (principles for structural reliability and design), the earlier SNIP/SP editions (for example, СНиП 2.01.07‑85* and the previous СП 20.13330.2011), and other SPs dealing with specific actions (snow, wind, seismic design codes and soil/ foundations standards). The official SP record also lists successive amendment documents that modify numerical coefficients and certain clauses.

FAQ

Q: What is this standard?

A: SP 20.13330.2016 is the Russian "Свод правил" (set of rules) titled "Нагрузки и воздействия" — a national regulatory document that prescribes how loads and actions are assigned and combined for structural design.

Q: What does it cover?

A: It covers classification of loads, methods and coefficients for determining imposed, snow, wind, temperature and settlement loads, rules for accidental and special loads, and combination rules for ultimate and serviceability limit states used in building and structure calculations.

Q: Who typically uses it?

A: Structural engineers, building designers, calculation specialists, regulatory authorities, and software developers producing tools for structural analysis and code‑compliant design documentation.

Q: Is it current or superseded?

A: The 2016 edition is in force (entered into force on 4 June 2017) and has been maintained through a series of official amendments/changes issued by the Ministry of Construction. Official lists of amendments are published with the document; published editorial releases and technical publishers show subsequent numbered changes (for example, amendments approved in 2018–2023 and further updates reported through 2024). Users should consult the latest published edition (including amendments) to ensure they apply current numerical values and clauses.

Q: Is it part of a series?

A: Yes — it is part of the system of SP (Свод правил) documents and aligns with other national design codes and GOST standards addressing reliability, actions and loads, and is the updated editorial continuation of older СНиП and СП documents on loads and actions.

Q: What are the key keywords?

A: Loads, actions, combination of loads, permanent load, long‑term and short‑term actions, snow, wind, temperature, settlement, accidental loads, limit states, structural reliability.
