The reinforcement with steel of this structure is too large.

The design is not new, exist over 50 years.

In Italy are those igloos been around since the 1960s, completely without steel reinforcement and with spans up to 15 m. Die walltickness ist about 5 cm, only concrete, only with rabbit wire structurally reinforced..

Not sure why you consider the steel too large? Whether it is a tornado, hurricane or earthquake you should have steel in the concrete or experience what Haiti did with non reinforeced concrete

This may seem like a silly question, but, is the airform holding the rebar in shape or is rebar preshaped?

[buck3647]

rebar is bent to follow the airform so the airform is actually the form

Does the outside need to be painted every so often? Or is the color permanant..

What about mold on the outside in hot humid weather?

[buck3647]

The foam and coating over the foam will only need to be hosed periodically or run a copper ring around the top to let the mineral drip over the dome with every rain.

Exterior needs recoated periodically like any other UV prone material.

Holly cow. Bet you could park a bulldoser on the dome when it's finished.

[ramiroarenapanama]

That is correct against huricanes a.s.o, but I told from Italy, sorry.

air form really isn't needed :) if you are professional working with steel
