This paper illustrates the ongoing revision of the Chapter 8 for the seismic design of timber buildings of Eurocode 8, which is currently under discussion within the CEN/TC250/SC8 'Design for Earthquake Actions', subgroup WG3 'Timber'. The current edition of this Chapter, which was published in 2004, is very short (only 5 pages) and incomplete in many parts, especially when referring to the design of new construction systems recently developed and not yet included in the 2004 edition. The most important features of the new version under discussion will be presented herein and the recent update discussed, following the first results of the revision work already presented in 2015.
