Eurocodes: Building the future

Standardisation works for 2G Eurocodes

The European Commission issued the mandates M/466 and M/515 to CEN for amending the existing Eurocodes and extending the scope of structural Eurocodes.

Incorporation of scientific developments

Extension of existing rules

The standardisation work covers the extension of existing rules for the assessment of existing buildings and structures and their strengthening, together with the extension of existing rules for robustness.

Recent results of international studies and research programmes and practical experience from scientific and technical associations relevant to innovation, e.g. performance-based designsustainability concepts and traffic loads, are incorporated in the Eurocodes second generation drafts.

Other topics for which information has been developed isthe determination of material and resistance factorsserviceability for buildings and bridges; fatigue verification; improving the fire safety engineering approach.

Where relevant, ISO standards are expected to be adopted to supplement the Eurocodes family, for example atmospheric icing of structures and actions from waves and currents.

Climate change

The 2013 EU Adaptation Strategy had already identified standards as potentially important to guarantee the resilience of infrastructures to climate change, in particular regarding the following: transport infrastructure, energy infrastructure and constructions/buildings. In this context, it was relevant to identify which standards needed to be promoted and/or amended to take better account of current and future impacts of climate change in infrastructure investment decisions.

A technical report has been developped analysing and providing guidance for potential amendments for Eurocodes with regard to structural design addressing relevant impacts of future climate change, both general and material-specific.

Facilitating practical implementation

In the context of the Eurocodes second generation standardisation work, auxiliary guidance and background documents is being developed to facilitate feedback from stakeholders and the practical local implementation wherever necessary.

An essential activity taking place is the assessment of the links to harmonised product standards developed under the framework of the Construction Products Regulation or other European standards, in particular with regard to any discrepancies between the calculation methods of the Eurocodes and the declaration of performance for products that bear the CE mark.
