This Technical Specification (CEN/TS) was approved by CEN on 22 August 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,

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/adopte

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