Elevator Cube

Elevator Cube

Elevator Cube

(OP)
anybody knows how to design a elevator cube, the load, all the considerations that we have to take at the momento to design the an elevator cube, thanks you

RE: Elevator Cube

What's an elevator cube.  Is that a set of elevators 3 wide x 3 deep x 3 high?  Or are you talking about the elevator car?

RE: Elevator Cube

Usually an elevator supplier has all the dimensions for each car and details for alignment, guides and support. They are usually unique.

Could this possible be an open (3 sided) elevator system that does not stop (hop on and hop off quickly) at a floor and is just a platform on a continuous mechanical system?

If it is a system that that stops between the floors and every other stop (2.5, 4.5, etc. stops), so that usually requires a larger size car.

what i mean with cube elevator is the structure that support the elevator system, the walls that are around the elevator, in mexico we call it cube elevator, sorry i dont know the translation to english, sometimes we can design this structure with shear walls, but in this case i dont need a shear wall, but i dont know how to design this structure, that what i mean, I really appreciate your help.

Elevator shaft?

RE: Elevator Cube

You will need to know what type of elevator you are installing: Hydraulic, roped, machine room less, speed, door arrangement, etc...

Then I recommend going to 3 or so elevator providers and get their drawings for that type of elevator: Kone, Thyssen Krupp, Otis, etc...

The loads are provided on the elevator drawings.  They will include vertical elevator loads (on the rope or hydraulic cylinder), compression cylinder impact at the bottom, lateral rail loads and vertical rail loads.

Things to watch for are the hoist beam, sills to the elevator at each floor and blockouts for buttons and signs.   

RE: Elevator Cube

what teguci said, then pick your material of choice...masonry, concrete, steel, wood, etc. Sometimes the floors can be load bearing on the cube too.  

RE: Elevator Cube

Elevator shafts also have to be built out of fire rated materials and/or fire rated details, over and above the criteria that Teguci suggested.  Otherwise, they become a large chimney the full height of the building in a fire, spreading the fire from floor to floor, very dangerous.  By the very nature of the way they are built and located, many elevator cores are used to provide lateral strength for the building; or by the nature of their lateral stiffness they attract a high percentage of lateral load, so this must be considered in their design.  If you don't need them as shear walls (lateral strength) you use materials and details which only carry the other loads and don't attract the lateral loads.

Hire a structural engineer who knows what he/she is doing!!
