On the lower left is a photo of a ferrocement dome we built in Orchidland years ago. http://www.pacificgunite.com/ferrocement...ction.html No worries about unreinforced dome collapsing in an earthquake. There is plenty of steel in there. My engineer told the owner that if a hurricane was coming he was heading over to her pplace.
