The first floor my proposal is structured independently of the second floor. The first floor structure consist
of of W 10 by 50 steel columns with W 16 by 26 steel beams.
The second floor is supported by reinforced concrete cores rather than columns. And rather than
spanning the short dimension using steel beams I chose to use 45 by 4 foot 16 in thick hollowcore
planks. These planks rest on top of steel trusses positioned inbetween the concrete cores in the long
direction.
The roof of the second floor is supported by two large steel and or concrete trusses that runs along the
perimeter of the second floor in the long direction.

I also have yet to decide whether or not I want to use the hollowcore planks again for the roof to remove
the need for columns or whether a thinner metal deck would be more appropriate. If I chose metal deck
for the roof this would obviously require me to add columns.
Hollowore Plank
I like the choice of prestressed hollowcore plank to support the second level because it reduces the
need to for steel beams and allows for a more compact section.
The typical size of each plank is 4 by 50 with the exception of a few planks that vary. While this may
seem too big for transport I figure that there may be some way trains can be used to transport these
pieces to the site.
