European foreword
This document (EN 1993-1-6:2007/A1:2017) has been prepared by Technical Committee CEN/TC 250
“Structural Eurocodes”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2018, and conflicting national standards shall be
withdrawn at the latest by April 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,

1 Modifications to the Foreword
In the Foreword, in the section “National Annex for EN 1993-1-6”, add the following entries into the list at
the appropriate places:
“
– 6.2.1(6)”;
and
“
– 8.6.3(5);”.
In the Foreword, in the section “National Annex for EN 1993-1-6”, replace:
“
– 8.7.2 (7)
– 8.7.2 (16)
– 8.7.2 (18) (2 times)”
with:
“
– 8.8.2 (9)
– 8.8.2 (18)
– 8.8.2 (20) (2 times)”.
2 Modification throughout the whole standard
Replace “r ” with “R”.

3 Modification to 1.2, Normative references
In the list of the parts of EN 1993, replace “Part 1.1 :” with “Part 1.1:2005:”.
4 Modifications to 1.3, Terms and definitions
Replace the whole Entry 1.3.2.1 with:
“
1.3.2.1 plastic failure limit state (LS1)
ultimate limit state where the structure develops zones of yielding in a pattern such that its ability to
resist increased loading is deemed to be exhausted”.
Add a new Entry 1.3.5.3:
“
1.3.5.3 semi-membrane theory analysis
analysis that predicts the behaviour of an unsymmetrically loaded or supported thin-walled cylindrical
shell structure by assuming that only membrane forces and circumferential bending moments satisfy
equilibrium with the external loads”;
and renumber accordingly the former Entry 1.3.5.3 (as 1.3.5.4) and the following definitions in 1.3.5.
Replace the former Subclause 1.3.5.6 (newly renumbered as 1.3.5.7) with:
“
1.3.5.7 materially nonlinear analysis (MNA)
analysis based on shell bending theory applied to the perfect structure, using the assumption of small
deflections, as in 1.3.5.4, but adopting an ideal elastic plastic material law (idealised perfectly plastic
response after yield)”.
Replace the former Subclause 1.3.5.7 (newly renumbered as 1.3.5.8) with:
“
1.3.5.8 geometrically and materially nonlinear analysis (GMNA)
analysis based on shell bending theory applied to the perfect structure, using the assumptions of
nonlinear large deflection theory for the displacements and a fully nonlinear elastic-plastic-hardening
material law, where appropriate, and in which a bifurcation eigenvalue check is included at each load
level”.
Replace the former Subclause 1.3.5.9 (newly renumbered as 1.3.5.10) with:
“
1.3.5.10 geometrically and materially nonlinear analysis with imperfections included (GMNIA)
analysis with imperfections explicitly included, based on the principles of shell bending theory applied
to the imperfect structure (i.e. the geometry of the middle surface includes unintended deviations from
the ideal shape), including nonlinear large deflection theory for the displacements that accounts fully
for any change in geometry due to the actions on the shell and a fully nonlinear elastic-plastic-
hardening material law, where appropriate
Note 1 to entry: The imperfections may also include imperfections in boundary conditions and residual
stresses. A bifurcation eigenvalue check is included at each load level.”.
5 Modifications to 1.4, Symbols
Delete the NOTE in Paragraph (12).
In Paragraph (12), replace the following line:
“α elastic imperfection reduction factor in buckling strength assessment;”
with:
“α elastic buckling reduction factor in buckling strength assessment;
α geometric reduction factor;
G
α imperfection reduction factor;”.
I
In Paragraph (12), replace the following line:
“χ buckling reduction factor for elastic-plastic effects in buckling strength assessment;”
with:
“χ elastic-plastic buckling reduction factor for elastic-plastic effects in buckling strength
assessment;”.
In Paragraph (12), replace:
“χ overall buckling resistance reduction factor for complete shell;”
ov
with:
“χ overall elastic-plastic buckling reduction factor for a complete shell;”.

6 Modification to 2.2.5, Linear elastic bifurcation analysis (LBA)
In Paragraph (1), replace “8.6 and 8.7” with “8.7 and 8.8”.
7 Modification to 2.2.6, Geometrically nonlinear elastic analysis (GNA)
In Paragraph (2), replace “8.7” with “8.8”.
8 Modification to 2.2.7, Materially nonlinear analysis (MNA)
In Paragraph (1), replace “8.6 and 8.7” with “8.7 and 8.8”.
9 Modification to 2.2.8, Geometrically and materially nonlinear analysis (GMNA)
Replace Paragraphs (1) and (2) with the following ones:
“(1) The result of a GMNA analysis, analogously to 2.2.7, gives the geometrically nonlinear plastic failure
load of the perfect structure and the plastic strain increment, that may be used for checking the limit
states LS1 and LS2.
(2) Where compression or shear stresses are predominant in some part of the shell, a GMNA analysis
gives the elasto-plastic buckling load of the perfect structure. This perfect shell buckling load should
always be determined when the limit state LS3 is verified using GMNIA analysis, see 8.8.”.
10 Modification to 2.2.9, Geometrically nonlinear elastic analysis with
imperfections included (GNIA)
In Paragraph (1), replace “8.7” with “8.8”.
11 Modification to 2.2.10, Geometrically and materially nonlinear analysis with
imperfections included (GMNIA)
In Paragraph (1), replace “8.7” with “8.8”.
12 Modification to 3.3, Geometrical tolerances and geometrical imperfections
