[TowerTalk] Need some help

[kr7x1 at verizon.net]

Ruslin:

You need to get a copy of TIA-222-G. This is the latest edition of "Structural Standard for Antenna Supporting Structures and Antennas."

You will find all you need in this standard which is referred to by the IBC as the appropriate national standard for these types of structures. This coupled with the design wind velocity, seismic criteria, and any icing criteria will give you what you need.
