0 Introduction
0.1 Introduction to CEN/TS 1993-1-101

EN 1993-1-1:2005 ‘Design of Steel Structures — General rules and rules for buildings’ included two

methods for the determination of interaction factors used for the verification of the buckling resistance

of members under bending and axial compression force, which were provided in two separate Annexes

A and B.

During the revision of EN 1993-1-1:2005, the standardization committee CEN/TC 250/SC 3 took a

decision to retain the method provided in Annex B in EN 1993-1-1:2022 and to move the method of

Annex A into a separate document, i.e. this document, for reasons of ease of use, without significant

modifications.

This document is therefore to be considered as an alternative method to the one given in

EN 1993-1-1:2022. Its applicability can be defined for each country, by the National Annex of

EN 1993-1-1:2022.

This document, which was prepared in line with the Eurocodes, is intended for use by designers, clients,

manufacturers, constructors, relevant authorities (in exercising their duties in accordance with

national or international regulations), educators, software developers, and committees drafting

standards for related product, testing and execution standards.

NOTE Some aspects of design are most appropriately specified by relevant authorities or, where not

specified, can be agreed on a project-specific basis between relevant parties such as designers and clients. The

Eurocodes identify such aspects making explicit reference to relevant authorities and relevant parties.

0.2 Verbal forms used in the Eurocodes

The verb “shall" expresses a requirement strictly to be followed and from which no deviation is

permitted in order to comply with the Eurocodes.

The verb “should” expresses a highly recommended choice or course of action. Subject to national

regulation and/or any relevant contractual provisions, alternative approaches could be used

0.1 Introduction to FprCEN/TS 1993-1-101

EN 1993-1-1:2005 ‘Design of Steel Structures — General rules and rules for buildings’ included two

methods for the determination of interaction factors used for the verification of the buckling resistance

of members under bending and axial compression force, which were provided in two separate Annexes

A and B.

During the revision of EN 1993-1-1:2005, the standardization committee CEN/TC 250/SC 3 took a

decision to retain the method provided in Annex B in EN 1993-1-1:— and to move the method of

Annex A into a separate document, i.e. this document, for reasons of ease of use, without significant

modifications.

This document is therefore to be considered as an alternative method to the one given in

EN 1993-1-1:— . Its applicability can be defined for each country, by the National Annex of

EN 1993-1-1:— .

This document, which was prepared in line with the Eurocodes, is intended for use by designers, clients,

manufacturers, constructors, relevant authorities (in exercising their duties in accordance with

national or international regulations), educators, software developers, and committees drafting

standards for related product, testing and execution standards.

NOTE Some aspects of design are most appropriately specified by relevant authorities or, where not

specified, can be agreed on a project-specific basis between relevant parties such as designers and clients. The

Eurocodes identify such aspects making explicit reference to relevant authorities and relevant parties.

0.2 Verbal forms used in the Eurocodes

The verb “shall" expresses a requirement strictly to be followed and from which no deviation is

permitted in order to comply with the Eurocodes.

The verb “should” expresses a highly recommended choice or course of action. Subject to national

regulation and/or any relevant contractual provisions, alternative approaches could be used/adopted

where technically justified.

The verb “may" expresses a course of action permissible within the limits of the Eurocodes.

The verb “can" expresses possibility and capability; it is used for statements of fact and clarification of

concepts.
0.3 National annex for FprCEN/TS 1993-1-101

The applicability of this document can be defined for each country by the National Annex of

EN 1993-1-1:— .

The National Annex can contain, directly or by reference, non-contradictory complementary

information for ease of implementation, provided it does not alter any provisions of the Eurocodes.
