RE: Steel Antenna Towers.

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The wind loads are based on the projected area of one face of the tower
(just as in the UBC).  The Cf factor accounts for the other faces.  It's
easiest to apply the wind load on the tower and appurtenances as point loads
at the panel points for overall tower analysis and then come back and check
individual members for antenna or ladder loads that occur mid-span.  By the
way, I think the latest EIA is version F.

I sent the following request on Sunday but there is no response for the last
two days. I hope my knowledgeable and experienced colleagues will respond.
