Background
Preparatory work for drafting the forthcoming major revisions to Eurocode 8 began some time ago, with the formal establishment of CEN Project Teams to carry the process forward expected to take place early in 2014. It will take at least six years before an agreed version of the standard is ready to be ratified; however, the broad outlines and scope of the work are already defined in the proposals that CEN has submitted to the European Commission. Moreover, recognising the need and desire by practising engineers for stability in code provisions, there is a general desire by CEN to limit the extent of revisions to the Eurocode suite at this time. However, EC8 is in many ways a special case among the Eurocodes, because the underlying practice of earthquake engineering is evolving much more rapidly and radically than is the case for practice applying to the other Eurocodes.

It is therefore likely that the adopted version of EC8 which results from the evolution process in around 2020 will fall some way short of both the state of the art and state of practice in earthquake engineering at that time. There is a need to look beyond the forthcoming evolution process to define a direction for EC8 which includes a longer timescale than the current enquiry period, and which is not limited by the current CEN proposals. The task of the proposed working group would be to set out the broad characteristics of EC8 for the year 2025. The working group would comprise a small group of academic engineers and design practitioners, drawn from both high and low seismicity regions of Europe. A similar review was carried out by Californian earthquake engineers in 1995, to produce the Vision 2000 report (SEAOC, 1995) which successfully set out a path for radical revisions to the US seismic codes of the 21st century.

1) Review state of practice and state of art methods in the design of new seismic resistant buildings currently employed by European engineers, and identify the ways in which EC8 currently does not address these methods.
