I'm working on an art project, the main structure of which will be a 30' open air square. The square will be formed by fabric hanging from guy-wires running between each of the four corners which will be 8' tall poles. There will likely be an extra pole or two between each 30' span for support.
Regarding the guy wires, I'm planning for them to support both the load of the fabric and to hold the shape of the structure. My issue is, I'm not sure how to anchor / secure the guywires to the poles themselves, and then to the ground so that they provide sufficient support for the structure (esp considering that the fabric will probably catch some wind). I'm thinking that two guywires will meet at each corner (one per side), and then be joined by a single cable which will run diagonally down to a stake. Does that sound like it would support the load from all directions (given proper gauge wire)? I know its hard to imagine without a picture so I'll post one up once I can sketch it out.
Thanks for any help / advice you might have.
