Full title and description

STB DIN EN 1991-1-7:2010-12 — Eurocode 1: Actions on structures - Part 1-7: General actions - Accidental actions. German version EN 1991-1-7:2006 including corrigendum AC:2010; provides rules and procedures for assessing and designing for accidental actions (impacts, collisions, explosions and localised failure) on buildings and civil engineering works.

Abstract

This standard defines classification of accidental actions, design situations and procedures for determining design values for impacts (vehicles, ships, derailed trains, helicopters), gas explosions and other accidental events. It sets out strategies for preventing disproportionate collapse by either designing for identified accidental actions or by limiting the consequences of an undefined local failure, and includes informative annexes on localised failure and risk assessment.

Scope

EN 1991-1-7 provides strategies and rules to safeguard buildings and civil engineering works against accidental actions. The scope covers assessment of actions resulting from accidental human activity and external events — including impact and collisions (wheeled vehicles, ships, derailed trains), helicopter impact on roofs, and gas explosions — and gives procedures for risk analysis and technical measures to reduce consequences and avoid progressive collapse. Informative annexes give guidance on design for consequences of localised failure and on risk assessment.

Key topics and requirements

• Classification of accidental actions and definition of symbols and terms.
• Design situations and principles for robustness against disproportionate collapse.
• Impact actions: assessment methods for pedestrian/vehicle/vehicle-structure collisions and dynamic loading.
• Explosion actions: guidance for gas explosion load estimation and structural response.
• Design approaches: (a) design for identified accidental actions; (b) design to limit the extent of local failure for unspecified causes.
• Informative annexes on design for localised failure and on risk assessment; provision for national annexes and nationally determined parameters.

Typical use and users

The standard is used by structural engineers, building designers, safety and risk engineers, forensic engineers, code authors and national standards bodies when assessing accidental loading and designing building robustness. It is also used by regulatory authorities and contractors where accidental actions (impacts, explosions, progressive collapse risk) must be managed in design or retrofit projects.

Related standards

Part of the Eurocode 1 series (EN 1991) and intended to be used alongside EN 1990 (Basis of structural design) and other EN 1991 parts (e.g., 1-1 to 1-6 for other actions). National Annex documents (e.g., DIN EN 1991-1-7/NA versions) and subsequent amendment DIN EN 1991-1-7/A1:2014 provide nationally determined parameters and updates.

FAQ

Q: What is this standard?

A: DIN EN 1991-1-7:2010-12 is the German-adopted Eurocode document that sets out rules and procedures for assessing and designing structures against accidental actions (impacts, explosions and other extraordinary actions). It is the German version of EN 1991-1-7:2006 with corrigendum AC:2010.

Q: What does it cover?

A: It covers classification of accidental actions, design situations, methods for impact and explosion assessment, strategies for preventing disproportionate collapse (design for identified actions or limiting local failure), and informative guidance on risk assessment and localised failure consequences.

Q: Who typically uses it?

A: Structural and design engineers, safety/risk engineers, standards committees and regulatory bodies use it when accidental loading or robustness against progressive collapse must be considered in building and civil engineering design.

Q: Is it current or superseded?

A: The 2010-12 DIN adoption is a current national publication of EN 1991-1-7:2006 as amended by AC:2010; it has been subsequently modified by amendment A1:2014-08 and is used in conjunction with national annexes that may be updated. Users should check the applicable national annex and any later amendments before design.

Q: Is it part of a series?

A: Yes — it is Part 1‑7 of Eurocode 1 (EN 1991), the Eurocode series covering actions on structures; it is intended to be used with EN 1990 (basis of design) and the other EN 1991 parts addressing variable, permanent and exceptional actions.

Q: What are the key keywords?

A: Accidental actions, impact, explosion, robustness, disproportionate collapse, localised failure, risk assessment, Eurocode 1, national annex.
