Footnotes:
* All masts employ the same M30, 1220mm length foundation bolt, hot spun galvanised, Grade 8.8.
** Site wind speed: this figure is based on an assumption that site is 1km from the sea at an altitude of 0m.
*** Hourly mean is the UK standard for wind loadings. Many continental European countries specify “10-minute mean” wind speed, which varies slightly. Contact UK sales office for more information.
**** 3 second gust is the wind load design velocity used in many countries.
† For complete foundation details, refer to pages 50-55; the overturning moments (OTM) and shear forces are rounded up to the next level to calculate the suitable foundations for the mast. There is a choice of either passive or non-passive foundations, both of which are non-reinforced. For a reinforced foundation design, use the same code but with ‘R’ replacing the ‘M’ and ‘P’ will fulfill the requirement.
