how to dimension goat iron to cover attic i

[odisseo 18]

the cover has 2 bonnets must have a long side 7,30 meters horizontal and the other 4,20m long side pillars 2,10 meters the central 3,70 as I rule. total 11,50, + laterally I have to have a perimeter margin of 58 cm per grondaia and pluvial as I have to adjust? how would you do it, the attic is at sea level is not stressed by the load of snow, is a bit windy the area, regarding current arches and countervents as I rule? thanks to those who want to answer and intervene

I would say that if you don't want me to run the dead and the abuse you have to turn to an enabled architect/geometra. You don't risk it on these things.

does not have snow load?!? Mah.. be careful....maybe he doesn't even have a seismic zone?!?! And then he comes down?

thank you all gentlemen users, for all your precious words, I was aware of all this I wanted only if there were any technical indications, I am told that some specialized firm builds self-supporting roofs in mounting kits, in short, I would need a simple functional and economic solution thanks again apologize if I was too pretentious and I wanted to take advantage of your skills and professional excuses
eurocode 9 uni env 1999-1-1:2002 for standard snow loads 150dan/m2 and wind 90 dan/m2, the structure is certified according to 1090

Hi.
First I have to understand what you want to do, because I don't understand.
Do you need to remake the roof of a house? or is it a simple outdoor gazebo as in the photo?

in the first case it serves a certain shortness, precise calculations signed by a suitable technician, verification of the existing etc. etc.
in the second case the gazebo must be checked, but it is a level of difficulty to be faced without problems. However it looks good usually it is necessary a building permit for which still needs the enabled technician. many people mount the gazebo mounted by the carpenter or blacksmith without anyone complaining, but legally it is an abusive work.

If you want to make a constructive hypothesis of the gazebo, let us know what you mean and see what we pull out.

I don't have to build a gazebo I found that photo as a type of solution, I found a company that builds self-supporting roofs in rigger type mounting kits with modular structures in reticoar structures, however from the loft 8 shots from 22mm http://www.tettofacile.it/focus/piano-casa-per-sottotetti.htmlWhat solution do you recommend? thanks for the precious advice
