Full title and description

SP 385.1325800.2018 — Protection of buildings and structures against progressive collapse. Design rules. Basic provisions (Russian title: СП 385.1325800.2018 «Защита зданий и сооружений от прогрессирующего обрушения. Правила проектирования. Основные положения»). This regulatory document establishes basic provisions and design rules intended to ensure that buildings and structures of normal and increased responsibility are protected against progressive (disproportionate) collapse.

Abstract

SP 385.1325800.2018 defines principles, assessment approaches and design requirements to reduce the risk of progressive collapse in buildings and structures of classes KS‑2 and KS‑3. The document sets out responsibility classes, acceptable analysis methods (including alternate load path and dynamic approaches), design and detailing measures to preserve overall structural integrity when one or more primary elements are lost, and exclusions and application limits for special structure types. It is issued by the Ministry of Construction of the Russian Federation and entered into force at the beginning of 2019.

Scope

The scope covers basic provisions for the design of buildings and structures of normal and elevated responsibility (classes KS‑2 and KS‑3) to ensure protection against progressive (disproportionate) collapse. The standard applies to a wide range of structural systems and establishes when and how progressive collapse assessments should be performed, while explicitly excluding certain classes of structures (for example, most transport and hydraulic engineering structures and objects classified as cultural heritage where separate rules apply). The document is intended for design of new structures and for certain assessment cases in reconstruction projects where progressive collapse consideration is required.

Key topics and requirements

• Definitions and classification of progressive (disproportionate) collapse and responsibility classes (KS‑2, KS‑3).
• Criteria for when progressive collapse analysis is required and which buildings/situations are exempted.
• Permitted analysis methods (alternate load path procedures, removal-of-element scenarios, and dynamic/direct methods) and recommended modeling approaches.
• Design and detailing measures to ensure robustness and ability to redistribute loads after damage (redundancy, continuity, ties, and connections).
• Requirements for evaluation of load combinations, accidental actions and design scenarios relevant to progressive collapse.
• Procedures for documenting analysis, assumptions and safety checks in the project record.

Typical use and users

Primary users are structural and civil engineers, design organizations, project reviewers, building safety authorities, and consultants involved in structural robustness and safety assessments. The standard is used during conceptual and detailed design to determine whether progressive collapse protection measures are required, to carry out appropriate analyses, and to document required robustness and redundancy in project documentation.

Related standards

SP 385.1325800.2018 is part of the Russian system of Svod pravil (SP) and is used alongside other SP and national design codes addressing structural design, material-specific design rules, seismic design, and fire safety.

FAQ

Q: What is this standard?

A: It is a Russian Svod pravil (SP) — SP 385.1325800.2018 — that sets out basic provisions and design rules to protect buildings and structures against progressive (disproportionate) collapse.

Q: What does it cover?

A: It covers classification of responsibility levels (KS‑2, KS‑3), requirements for when progressive collapse assessment is needed, acceptable analysis approaches (alternate load path and dynamic methods), design and detailing measures to ensure structural robustness, and documentation requirements. Certain structure types (notably many transport and hydraulic structures and protected cultural heritage objects) are outside its scope.

Q: Who typically uses it?

A: Structural/civil engineers, design offices, technical reviewers, and regulatory authorities involved in building safety, robustness assessment and structural design in jurisdictions that adopt or reference Russian SP documents.

Q: Is it current or superseded?

A: The edition is SP 385.1325800.2018 (approved July 5, 2018) and was introduced into force on 06 January 2019. The document has received subsequent amendments and corrections recorded by standards distributors (revisions noted in 2019, 2021, 2022 and later updates in catalogue listings). Users should check the official registry or publisher for the latest amendment status before relying on the text for design.

Q: Is it part of a series?

A: Yes — it is issued as an SP (Svod pravil) and belongs to the body of Russian technical rules and standards for construction; it should be used together with other SP and national norms governing structural design, seismic and safety requirements. Specific cross-references and related SPs are listed in the official document and in registry/catalogue entries.

Q: What are the key keywords?

A: Progressive collapse, disproportionate collapse, robustness, alternate load path, accidental actions, KS‑2, KS‑3, structural design, СП 385.1325800.2018.
