[TowerTalk] Calculations

[Alan C. Zack]

And why does a major tower manufacturer stick to outdated UBC-97 50 
and 70 MPH wind calcs rather than the newer IBC-2000 specs.  UST did 
send me a nice set of drawings based on UBC-97 that my Bldg Dept said 
were great IF they were based on IBC-2000 instead.  I suppose some 
hams will order and install the towers without a Bldg Permit or some 
Bldg Depts still accept the UBC-97 specs, but why can't they provide 
what the Bldg Dept requires?
Even my local AES store tried to get the IBC-2000 specs for me and 
were also unsuccessful.
