Full title and description

STO 44577806.14.24-1-69-2013 — "Wind and snow loads of the Norilsk industrial region. Definition of standard and calculated values" (Russian: "Нагрузки ветровые и снеговые Норильского промышленного района. Определение нормативных и расчетных значений"). This territorial / organisation standard sets the normative and design values used for assigning wind and snow loads in the Norilsk industrial area.

Abstract

This STO defines the maps, parameters and calculation rules for normative and design (calculated) values of wind and snow loads specific to the Norilsk industrial region. It is intended to provide load values and local zoning information that supplement or specify national rules when designing buildings, structures and outdoor equipment in the Norilsk area.

General information

• Status: Active (document in force as an organisational/territorial STO).
• Publication date: 2013 (document identifier ends with -2013; original issue 2013).
• Publisher: Issued as an STO tied to organisation code 44577806 (used by the Norilsk industrial company group / GMK "Norilsk Nickel" territory standards).
• ICS / categories: Construction — actions on structures; territorial/organisational technical standard for environmental loads (commonly used with building design standards for loads and actions).
• Edition / version: STO original issue 2013 (no later formal revision published in the STO record shown).
• Number of pages: 16 pages (electronic PDF).

Scope

The standard applies to the Norilsk industrial region (Норильский промышленный район). It establishes the normative (S0, wg or equivalent local notation) and calculated values of snow and wind loads, provides local zoning (maps) and prescribes how those values are to be used in structural design and assessment for buildings, foundations, outdoor structures and certain types of equipment located in the region. The STO is intended to be used alongside national rules (for example СП 20.13330.2016 / "Нагрузки и воздействия") and territorial technical rules; where national regulations have been updated, designers should check for harmonisation or officially approved reconciliation of the STO with the current national code.

Key topics and requirements

• Local wind load zoning: maps and assigned characteristic wind pressures/velocities for the Norilsk industrial district.
• Local snow load zoning: ground snow weight values and coefficients for conversion to roof loads (normative and design values for different exposure/roof types).
• Definitions of normative (reference) and calculated (design) values and the conversion / safety factors to be applied in structural calculations.
• Application rules: how to apply the STO values in structural calculations and where the STO supplements or refines national rules for the Norilsk area.
• Instructions for resolving conflicts with later national documents (notes and commentary referencing national practice and amendments).

Typical use and users

Primary users are structural engineers, design institutes, project organisations and construction companies working in the Norilsk industrial region, as well as plant engineers and asset owners (including Norilsk Nickel group entities) responsible for safe design and operation of buildings and industrial installations in the area. The STO is referenced when local (territorial/organisational) load values are required in project documentation.

Related standards

Primary national references used together with or referenced by the STO include: - СП 20.13330.2016 "Нагрузки и воздействия" (updated edition of СНиП 2.01.07-85*), which is the national ruleset for loads and actions in Russia; designers should compare values and maps between the STO and СП 20.13330.2016 and its amendments. - Earlier territorial and regional documents on snow/wind loads (territorial СНиП/ТСН documents) that address extreme local conditions in Arctic and northern regions.

FAQ

Q: What is this standard?

A: It is an organisational/territorial standard (STO) titled "Wind and snow loads of the Norilsk industrial region. Definition of standard and calculated values" that defines local normative and calculated values for wind and snow loads used in structural design within the Norilsk industrial area.

Q: What does it cover?

A: The STO covers local zoning (maps) for snow and wind, prescribes characteristic values (ground snow weight, wind pressure/velocity), defines conversion/coefficient rules for roofs and structures, and gives guidance on applying those values in structural calculations for the Norilsk industrial region.

Q: Who typically uses it?

A: Structural engineers, project organisations, construction companies, plant/asset engineers and regional technical services operating in the Norilsk industrial district — including organisations within the Norilsk Nickel group — use the STO when localised load data are required.

Q: Is it current or superseded?

A: The STO is listed as an active organisational/territorial standard; however, national rules (for example СП 20.13330.2016 and its later amendments) have been updated since 2013. When national codes change, designers must check whether the STO remains applicable as issued or whether a formal reconciliation or updated edition is required for compliance. If national SP maps or values differ from the STO, follow the officially mandated procedure to determine which values govern for a particular project (contractual specification, regulator instruction or an approved deviation).

Q: Is it part of a series?

A: It is an STO (organisational/territorial standard) identified by the organisation code prefix (44577806) and a specific document number; STOs are typically part of a set of territorial/organisational technical standards addressing construction, safety and operation in a company's region of activity. This STO should be used together with national standards for loads and actions and with other regional technical rules where applicable.

Q: What are the key keywords?

A: Wind loads, snow loads, Norilsk, normative values, calculated values, STO, territorial standard, structural design, СП 20.13330.2016.
