Didn't I...? You mean what do I think about the follies in Behrut? Or about the wretched urbanism plot...!?...:-):-)
But then few is said here about the way the Mameluks designed space (I'm not speaking of the "style")!
But I won't say more...:-) (I have to stay a bit mysterious if I want to keep some students...And it promotes some usefuls researches in libraries..:-))
I'm just waiting a few years, when my students will start working there... I'm quite confident!...:-):-):-)
For the domes, and pionnering.. Er... I'm afraid I didn't understand the question...!
"Pionnering" structures of the bamboo sort are very well studied and can be calculated and engineered as any other type of material.. I've even seen a "synthetic" bamboo made of plastic composites - inner tube like those effervescent medical things in diameter, then around it a torsade of cathether tubes, then a wrapping of the very thin sheets of plastic ... The resulting "bamboo" without knots has an incredible strenght (but then you musn't play with matches) !
The 3D whatever alveolated fabric is also very well known and quite ancient... The "Mosquito" english WW II fighter-bomber had it's structure made with bakelited paper (we could say today paper armed plastic)... In 1948 some french architect used that technique for flooring, it's still there...!
But when you work with curved planes bearing stress, the angles of the honeycomb are no more identical and vary slightly... So it's more of a nuisance to use then the gain of weight...
My two cents...:-)
