Tsai Performance Center Piece: Materials and Dimensions

After doing some research into metals and looking at the space I decided that I wanted a textured bronze look to the sculpture. Below are two examples of the kind of textured bronze that I'd like to cut the pieces out of.

I really like the way that the textured bronze has varied color and is shiny but not chrome. I think the changes in color and the textural variations will make the pieces more interesting so the light will reflect of them in interesting way. 

Below are the dimensions of the space that I am designing the piece for. The space is not perfectly square but for the sake of the diagram we will make the assumption that 73 and 74.8 inches are close enough in value that the basics of the conclusions made from this data are reasonably accurate. 

From this you can see that the maximum distance from the central point that the piece can extend is about 52.3 inches but that is only at the corners of the space, so any radial waveform should be arranged such that any pieces that are longer than 36.5 inches should be concentrated in those corners and will need to be examined to confirm that they will fit into the space. 

If I make the assumption that each radial piece will have a width of about an inch, that the average length of the pieces would likely be around 30 inches, and that the thickness of each piece is about 0.1 inches then we can make a few assumptions about the final weight of the piece if it were to be made entirely of bronze. The weight of a solid circular sheet with these parameters is about 137 pounds. 

That means that I would need to find a way to mount a piece that weighs about 140 pounds. I looked into a few methods and most of them involved drilling a hole in the wall behind the piece, but I would need to do more research to figure out exactly how I would  mount the piece.
