Structural System / Facade

After the final tutorial with Scobie Alvis, I thought the problem of getting light into the rooms can be solved with a perforated skin. The pattern is informed by the previous opennings I have decided and the structural analysis done in SAP software.

The structural system of the building works similar to the Phaeno Center of Zaha Hadid. The slabs span between the two sides of the structural skin.Having the skin run through the middle of the floor clearly blocks the view of a 1.70 person. I would like to have a some of these opennings translucent just like the hotel rooms we've experienced in Japan; when the window becomes only a element of the building to let the daylight in, not act as an opening to view through.
The facade sinks into the building in this one, and the floors attached to the skin are not independent from this skin, the skin becomes "the edge" as it gets a volume through inner surface.
Rooms are sometimes hanging from this skin and at some point this skin extrudes to become the lift...

Plans / Structure

A quick study sequence showing the floors after refining the building. Move the arrow right to left after the animation loads to see whichever level you would like to check yourself manually.

Another sequence showing the waffle slab structure for the hotel. By using interior walls as structural walls, I'm trying to get a column free building. While 3 cores hold this waffle slab high, lower skin of the building will help to distribute the load until the ground level.

The last sequence shows only the circulation through the building.

Structural Studies / Connecting the Cores

I would like this middle part to act like a giant structural wall supporting two sides of the building.

Viewing from the south, eastern and western wings of the building would be balanced hanging onto the gray part which is the giant wall on the drawing above.

Structural Study / Dead Load Performance

This is a structural study only for the envelope of the building done in SAP10, it's possible to see which parts of the building is weak weighting the Dead Load on this animation.

Unfolded facade is a useful template to show the weak points of the geometry - as an object. The real structure of the building will not be depending on a structural facade since the building is not that large.
The famous right angled 3x4x5 triangle was formed by chance when I was looking for three continous vertical spaces which can accomodate the cores of the building. The center of gravity would not be in the middle of the building if all of the cores were same sized so I increased the size of the southern core (x) and gradually decreased the dimensions towards north (y and z) which moved the center of gravity for this triangle towards the center of the building.

From this drawing, you can see how these three cores are cutting through the building at different levels.
