Load bearing capacity of conduit geodesic domes

[Justin Kurtz]

Looking to build a geodesic dome out of conduit and wondering about enclosing the structure.  So far all I can find is links on building green houses, and I am interested in making this a house/house....Possibility of ferrocement, (though I'd prefer hempcrete) or even traditional building materials (mdc and shingled roof)

Thanks in advance.

I made a home use "conduit" and did use poliestirene panels with stuco and mesh.

I live in so warm place 45 celcius on summer.

Maybe i can help a little.

Search "domo tonanzy" in panoramio page.

See you.

Justin,

First off, welcome to the group.

As I'm sure you realize, many variables are involved, regarding
conduit size & thickness. Alternatively, at larger sizes, galvanized
fence piping can be employed. For both, you have to consider whether
the conduit/piping has a longitudinal seam, which can compromise the
strength. (Remember, the named materials are not rated for
"structural" use.)

You might find this thread, regarding the NEEM dome, of interest:
https://groups.google.com/group/geodesichelp/browse_thread/thread/3119f2c6a326e60a

Built of "fat" galvanized tubing, the NEEM dome was produced by Dome,
Inc. There are some photos in the thread; in the first post, and about
2/3rds of the way through the discussion. You might find the SIPS
discussion useful, as well, so don't skip those posts in the thread.
_______________________

Something to consider: The skin, or shell, of the dome can be
constructed so that it is, essentially, monolithic. The strength of
the dome is the shell, not the frame. The conduit serves only as the
framework for construction of the structural shell. This is THE
primary advantage of the ferrocement method you mentioned -- no
questionable reliance on the strength/weakness of conduit, for
structural integrity.
