Full title and description

SP 468.1325800.2019 — Concrete and reinforced concrete structures. Rules for ensuring of fire resistance and fire safety (Russian: СП 468.1325800.2019. Бетонные и железобетонные конструкции. Правила обеспечения огнестойкости и огнесохранности). This set of rules establishes methods, calculation procedures and prescriptive requirements to assess and ensure the fire resistance and fire safety of concrete and reinforced‑concrete structural elements and systems.

Abstract

SP 468.1325800.2019 provides thermal and structural assessment methods, tabulated data and simplified calculation procedures to determine fire resistance limits (loss of load‑bearing capacity, loss of insulation, critical temperatures) for concrete and reinforced‑concrete members (beams, slabs, walls, columns). The document also covers material behavior of concrete and reinforcement under elevated temperatures and gives recommendations for fire‑protective measures and design of fire‑protection systems for concrete elements. (Includes numerical tables, isothermal profiles and guidance for both standard and elevated fire exposures.)

Scope

The standard applies to design, assessment and retrofit of concrete and reinforced‑concrete structural elements and systems where fire resistance and fire safety must be ensured. It defines criteria and calculation procedures to determine fire resistance limits (insulation, integrity where relevant, and load‑bearing capacity) for members exposed to standard and non‑standard fire scenarios, prescribes use of tabulated data and simplified methods, and describes requirements for fire‑protection measures for concrete structures. The rules are intended for application in building design, reconstruction and evaluation of existing structures.

Key topics and requirements

• Material behavior of concrete and reinforcement at elevated temperatures, including critical temperatures and post‑fire residual properties.
• Thermal (heat‑transfer) calculation methods for concrete members under fire exposure.
• Procedures to calculate fire‑resistance limits by loss of load‑bearing capacity and by loss of insulating ability (including simplified and tabulated approaches).
• Assessment methods for slabs, beams, walls and columns under one‑, two‑ and four‑sided fire exposure.
• Rules for determination of reduced effective cross‑section (isotherm based) and coefficients to account for temperature effects on strength and creep after heating.
• Requirements and guidance for fire‑protective measures and application of fire‑protection materials for concrete and reinforced‑concrete elements.
• Specification of calculation safety factors, assumptions and limits of applicability for the simplified methods and tables.

Typical use and users

Primary users are structural and fire‑safety engineers, designers of reinforced concrete structures, specialists performing fire‑resistance assessments, and researchers working on structural fire engineering. The standard is used for design verification, retrofit and rehabilitation projects, preparation of normative technical documentation in construction, and academic/industrial research.

Related standards

SP 468.1325800.2019 is used alongside other Russian construction rules and SP documents governing concrete structural design (for example, the main set of rules for design of concrete and reinforced concrete structures SP 63.13330.2012) and with national fire‑safety rules and construction material standards. Practitioners commonly apply SP 63 (design provisions) in combination with SP 468 for fire‑related checks and details.

FAQ

Q: What is this standard?

A: It is a Russian "Svod pravil" (SP) — SP 468.1325800.2019 — providing rules and calculation procedures to ensure fire resistance and fire safety of concrete and reinforced‑concrete structures.

Q: What does it cover?

A: Methods to assess fire resistance (thermal analyses and structural checks), tabulated and simplified calculation procedures, material behavior of concrete and reinforcement at elevated temperatures, fire‑protection measures for concrete elements, and criteria for determining loss of load‑bearing capacity and loss of insulating ability.

Q: Who typically uses it?

A: Structural engineers, fire‑safety engineers, designers of concrete and reinforced‑concrete structures, specialists assessing existing buildings’ fire resistance, and researchers in structural fire engineering.

Q: Is it current or superseded?

A: The original SP 468.1325800.2019 was approved in late 2019 and introduced into force on 11 June 2020. It received Amendment No.1 (approved 28 Dec 2023) and the text is maintained as active with that amendment — check national registries for any later changes.

Q: Is it part of a series?

A: Yes — it is one of the SP (Svod pravil) series of construction rules developed under Technical Committee ТК 465 and is intended to be used together with other SP documents covering concrete design and fire‑safety requirements (for example SP 63.13330.2012 and other SPs addressing structural design and fire safety).
