This document discusses the progress and development of implementing Eurocodes. It begins with background on Eurocodes and then outlines Latvia's implementation plans from 2013-2014. It details the translation and development of national annexes required for Eurocode standards on structural concrete and steel by the end of 2014. The document also discusses the future development of Eurocodes, including revisions and the development of a new generation of Eurocodes by 2018. It provides information on the mandate for amending existing Eurocodes and extending their scope. Finally, it discusses the format of Eurocodes and their use in Europe and globally to remove trade barriers.

7. Mandate M/515 EN - Amending Existing Eurocodes
and Extending the Scope of Structural Eurocodes
In general
• extension of existing rules for the assessment of the existing buildings
and structures
• extension of the existing horizontal rules for robustness
• development of additional structural Eurocodes covering structural
glass members, FRP and tensile surface structures
• reduce the number of Nationally Determined Parameters (NDPs)
• improve the usability of Eurocodes by practical users
• incorporate recent results of international studies and the practical
experience from scientific and technical associations
• adoption of relevant ISO standards to supplement the Eurocodes
family (atmospheric icing of structures and actions from waves)
• development of auxiliary guidance document
• provide a clear and complete list of background documents used
during the standardization process
• simplification of rules for limited and well-identified fields of

8. Mandate M/515 EN - Amending Existing Eurocodes
and Extending the Scope of Structural Eurocodes
Detailed Work Programme (118 pages)
• Transfer of Basis of Design rules from EN1991-1-6, EN1991-3, EN 19914, EN 1993-3-1, EN 1993-3-2 and EN 1991-7 to EN 1990
• Vibrations – comfort of people – extend rules based on research
carried out since 1st edition of EN 1990
• A new set of codified rules for use of Non-linear F.E.M. in design
• Guidance for Lateral Stability of Structures
• The collection of available national snow and wind maps
• Establish a well-documented background information for
determination of partial safety factors
• The use of stainless steel reinforcement
• New rules for the verification / design of concrete structures
containing metallic and non metallic fibres
• Improvement of the serviceability rules for vibrations caused by
pedestrians
• Reinforcement of timber structures

9. Format of the Eurocodes
• The clauses in the Eurocodes are divided into Principles and Application Rules
• The Principles comprise:
General statements and definitions for which there is no alternative
Principles are preceded by the letter P and have the verb “shall”
• Application Rules are examples of generally recognised rules, which follow the Principles and
satisfy their requirements and have the verb “should”
It is permissible to use alternatives to the Application Rules given in Eurocode,
provided it is shown that the alternative rules accord with the relevant Principles and
are at least equivalent with regard to the structural safety, serviceability and durability

shall
within normative text, “shall” indicates
“requirements strictly to be followed in
order to conform to the document and
from which no deviation is permitted.”
(ISO/IEC Directives, Part 2)

jā..
normatīvā tekstā darbības vārds formā ar
priedēkli “jā-” norāda “prasības, kuras
stingri jāievēro, lai dokuments vispār
būtu ievērots, un no kurām nav atļautas
nekādas atkāpes” (ISO/IEC Direktīvas, 2.

should
within normative text, should indicates
“that among several possibilities one is
recommended as particularly suitable,
without mentioning or excluding others, or
that a certain course of action is preferred
but not necessarily required.” (ISO/IEC
Directives, Part 2) ISO/IEC 15408 interprets
'not necessarily required' to mean that the
choice of another possibility requires a
justification of why the preferred option
was not chosen.

vajadzētu
normatīvā tekstā vārds “vajadzētu”
norāda, ka “no vairākām iespējām viena
ir ieteicama kā sevišķi piemērota, pārējās
neminot vai nenoraidot” vai ka ”noteikta
rīcība ir ieteicama, bet nav katrā ziņā
obligāta” (ISO/IEC Direktīvas, 2. daļa);
ISO/IEC 15408 šo ”nav katrā ziņā
obligāta” interpretē tā: izvēloties citu
iespēju, jāpamato, kāpēc nav izraudzīta
ieteiktā iespēja!!!!!!!!!!
