birds nest stadium - what's "unwrapped steel"?

Posted by on August 10, 2008, 6:23 pm

There's lots of references to the new stadium in China hosting the
2008 Olympic (BirdsNest) saying it was made from X miles of "unwrapped
steel". Anyone want to describe what unwrapped steel really is? Is
it like HSS (Hollow Structural Sections)? Where can I find a picture
of what a typical cross section and connection looks like?

Exactly what it means there is no cover on the structural steel, roof or
walls etc.

No. It means the total arc length of all curved and straight lengths
of steel structural columns, channels,angles and beams etc. used in
its construction when they all are laid end to end... an indicator of
the size of Nest and amount of steel that went into the making of the
gigantic structure.

I used this group among others , many years ago, to publish a smart
new construction method I named 3D Honeycmb , I remember very few
realised that this method solved a number of problems, could see that
here was a newer before realised new way to use the computer and a
program , to allow the program to generate a smart assembled frame
structure. --- Main arguments in this group then, was ; "How do you
keep the rain out" . Today that method has been copied in several
instances in modern architecture, still with the more fame architect
stars no one ask "how do you keep the rain out".
Realy I find this sad, sad that the response for a great new idea, are
bad jokes.
