IHE Sign Structures Guide (September 2010)
Fully revised for new EU/BS standards.
Download or send an A4 s.a.e with stamps worth £1.50.
The design of supporting structures for traffic signs has been transformed by:
- The European standard BS EN 12899-1:2007 introduced different loads, safety factors and methods of calculation for sign supports, with wind pressure no longer uniform across the UK.
- Highway Agency standard BD 94/07 clarifies the design of foundations for signs and introduces the option of economical planted foundations.
- Passive safety: the 2010 Edition has a new chapter on this.
Buchanan's Signload Professional software reflects the Signs Structure Guide, co-authored by Simon Morgan.
- Other new material covers foundations on slopes, an introduction to wind funnelling effects, and spread foundation design to Eurocode 7 which, along with other structural Eurocodes, became mandatory earlier this year for public works.
