Full title and description

SP 20.13330.2011 — "Loads and impacts" (Russian: СП 20.13330.2011 «Нагрузки и воздействия»). This set of rules is an updated edition of the historic SNiP 2.01.07-85* addressing assignment of design loads, environmental actions and their combinations used in structural calculations.

Abstract

This code defines normative values, factors and combinations for dead, live (useful), snow, wind and other actions on buildings and structures; includes climatic zoning maps (snow and wind) and mandatory appendices for specific load cases (e.g., cranes). It was prepared as an updated revision of the earlier SNiP and aligned where possible with contemporary international practice.

General information

• Status: Replaced / not in force (document утратил силу); requirements have been superseded by the later edition SP 20.13330.2016.
• Publication date: Approved by order of the Ministry (MinRegion) 27 December 2010, came into effect in 2011 (commonly cited publication/effective date: 20 May 2011).
• Publisher: Issued under the authority of the Russian federal construction regulator (Ministry of Regional Development / Минрегион России at time of approval; later responsibilities transferred to Ministry of Construction).
• ICS / categories: Construction / structures of buildings (ICS 91.080 — structures of buildings; loading and calculation).
• Edition / version: Edition 2011 (designation SP 20.13330.2011).
• Number of pages: Typically published as ~96 pages in common electronic editions.

Scope

Establishes methods and numerical values for assigning loads, actions and their combinations to be used when designing and checking buildings and structures for ultimate and serviceability limit states (first and second group limit states), in accordance with the principles of GOST 27751. The scope includes normative provisions for permanent (dead) loads, variable (live) loads, snow and wind loads, exceptional actions, load factors, combination rules and the accompanying climatic zoning maps.

Key topics and requirements

• Definition and classification of loads: permanent, variable (useful), snow, wind, rain, temperature, soil and exceptional actions.
• Load combination rules and partial safety factors (reliability coefficients) for different load types and design situations.
• Normative formulas and coefficients for determining snow loads (including zoning maps and mu coefficients) and wind loads (zoning and tables in appendices).
• Special mandatory appendices covering bridge/overhead cranes, snow schemes and wind load provisions.
• Guidance for reduced (lower) normative values in specific interior-use cases, and provisions for applying additional or supplementary loads (e.g., partitions, equipment).

Typical use and users

Used by structural and civil engineers, building code compliance specialists, designers, project reviewers and construction authorities working on building and structural design in the Russian Federation or for projects using Russian normative practice. It served as the design basis for assigning loads and combinations prior to being superseded by the 2016 edition.

FAQ

Q: What is this standard?

A: SP 20.13330.2011 is a Russian "Svod pravil" (set of rules) titled "Loads and impacts" that defined how to assign and combine design loads for buildings and structures; it was issued as the 2011 edition updating SNiP 2.01.07-85*.

Q: What does it cover?

A: It covers classification of loads (permanent, variable/useful, snow, wind, etc.), numerical rules and coefficients for computing normative loads, load combination formulas, reliability coefficients (partial safety factors) and includes climatic zoning maps and mandatory appendices for special load cases.

Q: Who typically uses it?

A: Structural/civil engineers, designers and code compliance reviewers working on building calculations in Russia or on projects that refer to Russian normative practice—particularly prior to adoption of the 2016 edition. Designers apply its load values, combinations and maps in structural calculations.

Q: Is it current or superseded?

A: Superseded — SP 20.13330.2011 has been replaced by SP 20.13330.2016 and is generally shown as not in force (document утратил силу) in later official listings; users are advised to apply SP 20.13330.2016 (and its subsequent amendments) for current mandatory practice.

Q: Is it part of a series?

A: Yes — it belongs to the family of Russian construction codes and "Svod pravil" series that update and replace older SNiP chapters (this item updates SNiP 2.01.07-85* and is part of the SP 20.13330 series addressing loads and actions).

Q: What are the key keywords?

A: Loads, load combinations, snow load, wind load, reliability coefficients, climatic zoning, SNiP, GOST 27751, structural design.
