'But not long after there arose against it a tempestuous wind, called Euroclydon'

摘要

Firstly - when will it all happen? The general expectation is 2007 onwards. The draft National Annex for EN1991-1-4 is expected for public comment soon, so publishing early in 2007 seems reasonable. The other essential parts of the Eurocodes necessary for design should be in place (each with their all-important National Annex), to this sort of timetable. The draft National Annex to EN 1991-1-4 will be welcomed by many, as it makes the process of calculating wind loads familiar to BS 6399-2 users. Designers will recognise the process, despite the different presentation and nomenclature. As calibration exercises and the first few designs are complete, no doubt wrinkles will be discovered. These may be simply due to the heightened impact of wind in the basic combinations, as well as features of EN 1994-1-4 itself.
