Anyways it would be good if is a building just in case some evil dictator arises from nothing and his name starts with "c".

 

 

 

You mean other than Castro?

 

 

 

It also stands for Communism.

 

 

 

WE HAVE A WINNER!

The popularity of any given religion today depends on the victories of the wars they fought in the past.

It just seems like you're trying too hard with that many supports on it o_O. I wonder how long 'til it doesn't even look like a C >_<.

Fullmetal Alchemist, you will be missed. A great ending to a great series.

about how tall is it?

 

 

 

Around 41 stories, or about 679ft (226.3m). The "C" is around 35 stories high, or about 583ft (194.3m). Each floor is 12ft (4m) high. Inbetween each floor is 4.8ft (1.6m) high.

 

 

 

The building is surprisingly shorter than I had intended. :(

It looks like a hot air balloon now.

 

But yeah...Don't add too many supports. We built bridges at school once. They were about a foot long, but still...It was rather fun. And to experiment what would be a good bridge, we used this computer program where you could make virtual bridges and test them. I added way too many supports, and it sucked. On the other hand, I made one with a few supports and it worked a lot better. That's bridges, but I think it would go for buildings as well. (And I won the bridge thing...Yay...)

 

 

 

But now, I think you've nearly distributed the weight evenly. It should work then.

 

(It would be funny if for some reason, the O fell off the base thingy and started rolling throughout a city. But with those supports...Not likely...)

Yeah, I'm going to try and find a professional opinion on those bottom two supports. They look necessary, but something tells me with the elevator shaft, I could do without them. :-k

 

 

 

On the other hand, I rather like the elevator supports. Well, the left ones at least. The external elevator and people movers look kind of cool, sort of like La Grande Arche in Paris (but without the people movers):

the reason to many supports dont work to well is becasue it ends up adding more weight, then it does removing weight from the intial location.

 

 

 

and yes i would like to see that O roll through the city, but it would probaly just get crushed under its own weight <.< stuiped physicis

Hm...If you have some sort of rod running all the way straight down the middle, from the top of that circle, through the middle (The exact diameter), through the base, and deep into the ground...Perhaps that would work. I doubt it would be steady, but I think it would work.

 

This wouldn't get rid of the bottom supports, but if you slanted them the other way (Away from the the building), I think it would be sturdier. Maybe. But that would take more space.

 

And I wonder if anyone here is an architect. Perhaps you should find out.

Seeing as I'm about to graduate from uni with a degree in Civil Engineering in a month or so I might as well offer my contirbution.

 

 

 

Firstly, an architect would not be the person to consult about this - it would be a structural engineer. Thats a specialism within Civil Engineering. And like you mentioned, the lifts idea reminded me instantly of La Grande Arche at La Defense in Paris which we visited last year :)

Like most people have said, the main problem would be the cantilever action of the 'C' shape inducing large moments. You would most likely have to design your central vertical elevator as a supporting concrete/steel array of columns with a lot of bracing as you've shown.

 

 

 

The main approach that would be taken at this 'concept stage' is to try to figure out a suitable and economical load path for the forces and moments to be transferred from their points of action to the foundations. I wouldn't know enough to tell you how much more horizontal connections you'd need from the inside of the C to the main vertical column.

 

 

 

What your design does remind me of is this building that is being built by Arup in Beijing, China.

Note the oddly arranged bracings which have been specially positioned to take the wind loading. That building has also been designed to sustain seismic loading which is further impressive.

 

 

 

Sorry I can't help anymore, but strucutural engineering was never my favourite from Civils. I could ask my lecturers for their opinion if you like. I'd probably need a higher quality image though so it prints decently without pixelating. We did a steel strucutures and design module this year. :)

As long as the elevator shaft is also a major support it is fessible. I'm not an engineer (sp?) though my dads a mechanical.

i already mentioned the arch, does anyone read my posts?

You can't ever find a place that's nice and peaceful, because there isn't any. You may think there is, but once you get there, when you're not looking, somebody'll sneak up and write "(bleep) you" right under your nose. Try it sometime. I think, even, if I ever die, and they stick me in a cemetery, and I have a tombstone and all, it'll say "Holden Caulfield" on it, and then what year I was born and what year I died, and then right under that it'll say "(bleep) you."

That was one of my basic designs. So you're telling me this is feasible without the full circle, by creating an arched shaped base? :o

Yes Sir!

 

 

 

The current shape you have now would collapse under the pressure of the weight of the 'C' but with a arch shape the weight would be spread out and evenly distributed, making it possible for the 'C' to be held up. Its more complicatede then that but I won't go into details WHY the arch would work...

Could you make a quick sketch on MS Paint, I don't think I'm entirely comprehending you.

 

 

 

BTW (to those saying why make a "C"): what if the "C" stood for Colbert? :lol:

Colbert is a good man :^o

 

 

 

This is a quik sketch, it really demonstrates my paint skills :thumbsup:

 

 

 

I think you'll be able to see my idea easier now, the arch shape in the base evenly distributes the weight.

 

 

 

[the overlap was a mistake]

Me thinks that will work. As long as there is a arch the weight will be evenly distributed. This is just a theory though.

I know you said you wouldn't, but would you explain? Pretty please with sugar on top? :pray:

Look, I'm only 13 everyone I know doesn't even expect me to know this stuff! :wall:

 

 

 

I'll do my best though. :wink:

 

 

 

Almost everything that is made to take great pressure is rounded, look at the hull of a submarine, at extreme depths the submarine is able to take the pressure of all the water, due to its rounded shape. An arch is higher in the center than the ends, acting almost entirely on compression. An semi-circle arch can support more weight then a obtuse arch, which accomadates what you were thinking of. A flat top is a must because the flat top makes a stable platform for the weight to be distributed on. In your case, more than one arch may help to even out the weight better.
