Full title and description

ГОСТ Р 51273-99 — Сосуды и аппараты. Нормы и методы расчета на прочность. Определение расчетных усилий для аппаратов колонного типа от ветровых нагрузок и сейсмических воздействий (Vessels and apparatus. Norms and methods of strength calculation. Determination of design forces for column-type apparatus from wind loads and seismic effects).

Abstract

Standard that establishes methods to determine calculated (design) horizontal forces and bending moments acting on vertical cylindrical (column-type) vessels and apparatus caused by wind and seismic actions, including procedures for dividing the vessel into sections, determining natural vibration periods, and combining loads for different states (installation, testing, operation).

General information

• Status: Superseded / replaced — withdrawn from current use and replaced by the later unified standard GOST 34283-2017.
• Publication date: Approved by Gosstandart (Resolution No. 158) on 6 May 1999; date of introduction (effective date) 2000-01-01.
• Publisher: Gosstandart of Russia (State Committee for Standardization — later Rosstandart).
• ICS / categories: Chemical / process equipment classification (industry classifier commonly shown as 71.120.20 for equipment for chemical industry); relates to vessels and apparatus strength calculation.
• Edition / version: Original national edition 1999 (ГОСТ Р 51273-99); contains a text amendment (Изм. №1) published in 2006.
• Number of pages: Typical published text editions list about 16 pages (official distribution copies sold in Russian and English).

Scope

Applies to vertical cylindrical vessels and column-type apparatus installed outdoors and establishes calculation rules for wind and seismic loading: determination of natural vibration period(s), representation of the vessel as a cantilever (or other accepted calculation scheme), division into height sections (h_i ≤ 10 m), calculation of static and dynamic wind components and seismic design forces for regions with seismicity of 7 or more (MSK-64). Combinations of loads for different states (installation, test, operation) are handled according to related provisions.

Key topics and requirements

• Modeling column-type apparatus as an elastically restrained cantilever (or other agreed scheme) and subdividing the height into discrete sections for load application.
• Formulas and procedures to determine the fundamental period of vibration (several approximate and modal-analysis methods).
• Calculation of design bending moments and horizontal forces from wind loads — steady and fluctuating (pulsation) components, aerodynamic coefficients, height variation factors and spatial correlation.
• Calculation of design bending moments and forces from seismic actions — seismic coefficients, dynamic amplification (b coefficient), and application of accelerations to section mass centers.
• Rules for combining weight, wind and seismic actions for different operational states; tables and diagrams for q0 (wind pressure), aerodynamic factors, correlation coefficients and pulsation factors.
• Guidance on special cases (grouped apparatus on a common foundation, variable-section vessels, and conditions for applying approximate or detailed modal methods).

Typical use and users

Used by mechanical/pressure-vessel designers, structural and seismic engineers, process-equipment designers, verification and safety engineers in chemical, petrochemical, oil & gas and process plants, and by organizations preparing strength calculations for certification and inspection authorities. Engineering software and calculation tools for vessel strength/stability incorporate these procedures for column-vessel wind and seismic checks.

Related standards

Directly referenced: ГОСТ Р 51274-99 (Apparatuses of column type — norms and methods of strength calculations). The content and practices of ГОСТ Р 51273-99 have been incorporated and consolidated into later inter/state standards, most notably GOST 34283-2017 (which covers wind, seismic and other external loads for vessels and apparatus). Other related strength-calculation standards in the GOST family (e.g., GOST 34233.x series, GOST 14249-89, GOST 26202-84) address broader strength, shells, heads and special load cases.

FAQ

Q: What is this standard?

A: A Russian national (GOST R) standard from 1999 that provides methods to determine design horizontal forces and bending moments on vertical (column-type) vessels due to wind and seismic actions.

Q: What does it cover?

A: It covers modeling of column vessels (cantilever scheme or agreed alternatives), calculation of fundamental vibration periods, formulas for wind (steady and pulsating) and seismic loads, coefficients/tables for wind pressure and dynamic factors, and rules for load combination in different states (installation, testing, operation).

Q: Who typically uses it?

A: Pressure-vessel and structural engineers, designers in chemical/petrochemical and oil & gas industries, certification bodies and software vendors producing vessel-strength modules.

Q: Is it current or superseded?

A: Superseded — the approaches of ГОСТ Р 51273-99 have been consolidated into newer standards; GOST 34283-2017 is cited as the replacement/updated normative document covering wind, seismic and other external loads for vessels and apparatus. The original standard was approved 6 May 1999 and introduced 1 January 2000; a text amendment was issued in 2006.

Q: Is it part of a series?

A: Yes — it belongs to the GOST/GOST‑R family of strength-calculation standards for vessels and apparatus (related documents include ГОСТ Р 51274-99 and other GOST/GOST‑R and later GOST 34233 / GOST 34283 series covering general requirements, specific vessel types and load cases).

Q: What are the key keywords?
