Full title and description

STB DIN EN 1993-1-7 E 2023-03 — Eurocode 3: Design of steel structures — Part 1-7: Plated structures subject to out‑of‑plane loading. National adoption (STB) of the DIN/EN text (English/German), published March 2023. The document contains principles, calculation methods and design rules for stiffened and unstiffened plated steel elements when loaded transverse to the plate plane.

Abstract

This standard (part of Eurocode 3) provides rules and supplementary provisions for the design and verification of planar plated steel structural elements that are primarily subjected to out‑of‑plane actions (transverse loads). It covers strength, stability and failure modes of plates and stiffened plates, interaction between membrane and bending effects, and computational assessment methods suitable for engineering design under the limit state philosophy. It is intended for use together with EN 1993-1-1, EN 1990 and EN 1991 and with the appropriate national annexes.

Scope

The standard applies to the structural design of plated steel elements (stiffened and unstiffened plates) that are predominantly loaded by transverse (out‑of‑plane) actions. Typical applications include storage tanks, silos, gates, hopper walls, plate panels in bridges and other civil engineering members where transverse loads and resulting bending and membrane action determine capacity and stability. The document gives principles, calculation procedures (including numerical methods), verification checks and modelling recommendations. It supplements general rules in EN 1993-1-1 and must be applied in conjunction with EN 1990 (basis of design) and EN 1991 (actions).

Key topics and requirements

• Classification of plated elements: stiffened vs. unstiffened plates and appropriate modelling approaches.
• Design criteria for strength and stability under out‑of‑plane loading, including bending, shear and combined membrane–bending action.
• Buckling and post‑buckling behaviour of plates; shear buckling and local buckling of plate elements.
• Interaction formulas and verification rules for plates subjected to combined bending and membrane forces.
• Recommendations for imperfection modelling, residual stresses and influence of initial geometric imperfections.
• Use of numerical methods (finite element models), recommended boundary conditions, validation of models and required checks.
• Load combinations, partial safety factors and limit state verification consistent with Eurocode philosophy.
• Guidance for detailing of stiffeners, connections and support conditions relevant to plate behaviour.

Typical use and users

Engineers and designers of steel structures (structural engineers, tank and silo designers, bridge engineers, specialist consultants), fabricators checking plate capacity and detailing, researchers validating numerical models, code adopters and authorities, and inspectors who apply Eurocode rules to plated components subjected to transverse loads.

FAQ

Q: What is this standard?

A: It is the Eurocode 3 part for plated structures subjected to out‑of‑plane loading, adopted nationally as STB DIN EN 1993-1-7 E 2023-03 (published March 2023). It provides design rules and verification methods for plated steel elements loaded transversely.

Q: What does it cover?

A: Strength and stability rules for stiffened and unstiffened plates under transverse (out‑of‑plane) loads, buckling and post‑buckling behaviour, interaction of bending and membrane forces, imperfection and residual stress considerations, recommended numerical modelling and verification procedures, and relevant design checks within the Eurocode limit state framework.

Q: Who typically uses it?

A: Structural and design engineers, specialist fabricators, code assessors, regulatory bodies and consultants who design or verify plated steel components such as tanks, silos, hopper walls, certain bridge elements and other plate‑based structural members subject to transverse loading.

Q: Is it current or superseded?

A: This edition is the 2023 revision (designation 2023-03) and is current as the national adoption indicated by the STB prefix. Users should verify whether later amendments, corrigenda or national annex updates exist in their jurisdiction before applying the standard.

Q: Is it part of a series?

A: Yes — it is Part 1‑7 of the EN 1993 (Eurocode 3) series. It is intended to be used together with other Eurocode parts, most importantly EN 1993-1-1, EN 1990 and EN 1991, and with national annexes that set national parameters.

Q: What are the key keywords?
