Building a Dome out of Paper (and steel...and cement...)

Step 2 Rebar Work

We had a existing concrete slab so we just used metal plates anchor bolted to the slab and welded our rebar arches onto them. It was a little shaky getting the first few arches in the air, but the small dome is so manageable that it really was not a big deal. After the arches went up we started doing hoops around them. Everything is welded (a no no for rebar), but with a friendly engineer that can be dealt with. The welded rebar allows us to climb on the structure early in the building process. This makes it easier to tie remesh and lath to the dome.

pardon my ignorance why is welding rebar a no no? - been to the Philippines, Vietnam and Cambodia -- they use -weld various rebars to make water towers, radio station antenna masts/towers, lightning rod towers using re-bar (truss-like structures, triangles etc)???
