Fuerza Bruta

This is just a video clip of Fuerza Bruta - a show that gained a great deal of hype back on Broadway a few years ago. Before you begin thinking that it is a response to what could be a new Cirque show, this comes as a response to Ashley's earlier post on her design.  In this video clip you will see a small pool of water (with a transparent bottom) suspended over an audience (why make it safe and easy?).  Though not nearly as deep as the pool requirements for the studio project, it does highlight alternative strategies - most notably a series of trusses that effectively offer a structural "cage" (as Ashley was describing).  The trusswork could hold up the water however the trick becomes how such an assembly would be supported by the column(s)...

Structure HELP

So I need a little help. I'm trying to configure my structure to hold up the 9.5 metre deep pool.

I'm would like to maintain the same language throughout my building. . But at the same time, do not want to make a completely enclosed space within this transition point... essentially a cage...

Any suggestions would help in regards the most appropriate way to hold this pool in its given state.

Right now as you can see, I'm playing with parabolic sections from a hyperbolic form. Wouldn't I need to brace these sections together? Or is it not necessary... taking precedents from the OCAD building.
