Tall guyed mast 1

[Elite7]

Hi,

Does anyone know of any reference material for design of tall (over 300m) guyed masts?

Thanks in advance!

There is a software package available for that - can't remember the name. Google it.

Analyzing something like that by hand would take forever.

However - I would also make some hand calcs to verify ANY software output. If reactions agree and a couple of member forces check out - then it is probably right.

A positive reference is
Structural Engineering Handbook 4th ed.
Gaylord, Gaylord, Stallmeyer
McGraw Hill ed. NY, 1997
Section 30
Transmission and Communication Structures
Peyrot, Brinker

The program usually referred is RISA Tower, from RISA Technologies.

Referred Codes use to be

ANSI/TIA/EIA-222-F June 1996
Structural Standards for Steel Antenna Towers and Antenna supporting Structures

ANSI/TIA-222-G January 2006
Structural Standard for Antenna Supporting Structures and Antennas

Ishvaag -

Actually, the RISATower program is now tnxTower from Tower Numerics.

I would think the TIA G standard would be the best reference for the design of guyed monopoles. Certainly this is specific to communication towers. But, I'm not aware of other standards (for transmission lines or such) that go into quite as much detail as TIA.

 

[JoshPlumSE]

Correction.... I meant to say Guyed masts, not monopoles. You'd probably have some trouble getting a 300m monopole to work.

Thanks everybody!

A big thumbs up to boo1 for the example.

@Joshplum - we're doing tall self-supporting chimneys up to 275m, but those are in concrete.

PLS-CADD also has a TOWER module that handles TIA mast type guyed and self supporting lattice towers. You can generate TIA loads automatically.
