The EN Eurocodes
The EN Eurocodes are a series of 10 European Standards, EN 1990 - EN 1999, providing a common approach for the design of buildings and other civil engineering works and construction products. They are the recommended means of giving a presumption of conformity with the basic requirements of the Construction Products Regulation for construction works and products that bear the CE Marking, as well as the preferred reference for technical specifications in public contracts.

Questionnaire on requirements and use cases for integrating earthquake engineering and seismological data
The Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe (SERA) is a Horizon 2020-supported program aiming at reducing the risk posed by natural and anthropogenic earthquakes, based on innovative research and development projects. SERA also targets at providing improved access to data, services and research infrastructures for scientists and other professionals.
The European Plate Observing System (EPOS) is a long-term plan to facilitate integrated access/use of data, data products, software and services (DDSS) provided by heterogeneous infrastructures (Thematic Core Services, TCS) on solid Earth science in Europe. The project SERIES (Seismic Engineering Research Infrastructures for European Synergies) brought together Europe’s research infrastructures in earthquake engineering and enabled the automated integration of experimental results so that the earthquake engineering community can access data from an SERIES partner by using a single, unified centralized gateway, the Data Access Portal.
Building on the achievements in SERIES project and the developments in EPOS, one of SERA project tasks targets to a roadmap for the integration of earthquake engineering and seismological data, data-banks and informatics services to serve the needs of the research communities involved and beyond. A questionnaire has been developed aiming to collect information on requirements and use cases that will feed into the roadmap.
If your expertise lies within the fields of earthquake engineering or seismology, your input will be greatly appreciated. The questionnaire is accessible through EU Survey at this link.
JRC Technical Report: Standardisation needs for the design of underground structures
The design of tunnels has very unique characteristics but currently there are no available tunnel design standards or harmonized guidelines at European level. Tunnel design in Europe is being carried out based on national knowledge and experience with the use of industrial/client standards and guidelines, as well as with parts of the Eurocodes. However, the scope of the first generation of the Eurocodes covers buildings and some other civil engineering works, e.g. bridges but there are no parts devoted to the design of tunnels, as the Eurocodes do not include explicitly all underground structures.
JRC Technical Report: The implementation of the Eurocodes in the National Regulatory Framework
The report provides general information on the concept of the Eurocodes implementation in the regulatory system and discusses case studies of EU Member States that have successfully implemented the Eurocodes in their national regulatory system. The report also highlights the experience of designers on using the Eurocodes by presenting simple application examples. Moreover, the state of the Eurocodes implementation in the non˗EU Balkan countries is presented, based on the information exchanged and collected during the Workshop "The way forward for the Eurocodes implementation in the Balkans" (10˗11 October 2018 in Tirana, Albania), along with the activities of the Engineering Chambers in support of the Eurocodes implementation. The way towards the publication of the Second Generation of the Eurocodes, expected after 2021, is also discussed.
JRC Conference and Workshop Report: The way forward for the Eurocodes implementation in the Balkans
On 10th and 11th of October 2018, the workshop "The way forward for the Eurocodes implementation in the Balkans" took place in Tirana, Albania. The workshop was organized by the JRC within the Enlargement and Integration Action and was hosted by the General Directorate of Standardization of Albania. Approximately 100 participants (policy-makers, National Authorities & National Standards Bodies representatives, academics and practitioners) attended this two-day Eurocodes workshop. Lecturers and participants came from 12 different EU Member States (MS) and 8 non-EU Balkans countries (Albania, Bosnia & Herzegovina, the former Yugoslav Republic of Macedonia, Kosovo, Moldova, Montenegro, Serbia and Turkey). Distinguished experts gave presentations and participated in the round table discussions including CEN-CENELEC Director for Market Perspectives and Innovation, the Immediate Past Chairman of CEN/Technical Committee 250 (CEN/TC250) "Structural Eurocodes" and many CEN/TC250 experts actively involved in the development of the Eurocodes and also currently working on the 2nd Generation of the Eurocodes. The workshop was the first of a new series of Eurocodes dissemination and training activities in the Balkan region. It was an opportunity to collect and share the experience of EU Member States in the Eurocodes implementation in the national regulatory system through the presentation of case studies.

Booklet by European Commission: The European construction sector – A global partner>
The Joint Research Centre, the Enterprise and Industry Directorate General and the Energy Directorate General produced an updated version of the brochure on the integrated approach of European policies for the construction sector. It covers sustainability, in terms of energy and resource efficiency, health and safety issues for buildings, construction works and products. The brochure gives information on the available support schemes and financial instruments and highlights the benefits of international cooperation.
JRC Science for Policy Report: State of implementation of the Eurocodes in the European Union
The report presents the results of the enquiry on the implementation of the Eurocodes in the EU Member States and Norway, which was performed by DG GROW and DG JRC of the European Commission in 2014-2015. The analysis of the state of implementation of the Eurocodes in the EU Member States and Norway concludes that in 23 EU Member States and in Norway the Eurocodes are implemented. The identified restrictions imposed by existing National Regulations which define technical rules different from the provisions of the Eurocodes, indicate that there is need of a Commission Recommendation on the regulatory environment for use of the Eurocodes.
JRC Scientific and Policy Report: Eurocodes: Background & Applications. Design of Steel Buildings. Worked examples>
The present JRC report contains state-of-the-art training material on the structural design of steel buildings, with emphasis on worked examples. The technical papers here presented focus on specific parts of the structural design, namely basis of design, modelling of structure, design of members, connections, cold-formed steel, seismic and fire design and on sustainability aspects. The report intends to contribute towards the transfer of background knowledge and expertise on the Eurocodes, mainly the EN 1993, from specialists of the European Convention for Constructional Steelwork (ECCS) and of CEN/TC250/Sub Committee 3, to trainers at a national level and to Eurocodes users. The report includes a comprehensive description of Eurocodes rules and worked examples presented by the aforementioned specialists at the workshop “Design of steel buildings with the Eurocodes, with worked examples’’ that was held on 16-17 October 2014, in Brussels, Belgium.Download the whole report (13.3M)
