Stacking Tubes

[Berniedog]

Does anyone have the article by S.S. Safarian and E.C. Harris "Design of Stacking Tubes for Granular Materials" ?

Bernie,

I used to work for a company that designed them and I have a copy somewhere. I will search and get back to you. Another reference is Handbook of Concrete Engineering by Fintel,Chapter 15, Reinforced Concrete Chimneys.

I've looked for that as well in the past and couldn't find it. I'm curious to see Fintel's book... I've also been curious about "Structures and Granular Solids: From Scientific Principles to Engineering Application", and Ghali's, "Circular Storage Tanks and Silos" but am leery to buy them without justification at $160 and $250, respectively.

Does anyone else find it interesting that Bendog is helping out Berniedog on such an obscure topic? Maybe after my post Bevdog and Bertdog will chime in...

I'm still looking for Safarian and Harris. Another reference is ACI313 Standard Practice for Design and Construction of Concrete Silos and Stacking Tubes for Storing Granular Materials. I recall the maximum design case having to do with the removal of a 60 degree sector of material around the tube, causing an unbalanced lateral load, in combination with the belt pull forces at the top of the silo.

Who let the dogs out, woof woof.

 

[Berniedog]

Thanks. We do have ACI 313. It is always good to have other references.
Dogs are very smart. Engineers are relatively smart. Go Browns.

Berniedog,
Would you mind sharing the structure you are working on, is it new stacking tube or an existing? What industry will be using/or are using it? Heigth of it?
If is existing do you have a pic of that? Is it located in high windor high seismic?

Just curious. I am in the industy that has a lot and I am expecting similar thing comes in my plate.

Thanks

 

[Berniedog]

See attached. It is in a low seismic, low wind area

Berniedog (Structural, thank you for the info and DWG.
Did you ever get the paper or article you were asking initially?
I am interested reading that paper, don't know if it has a design example?

Where can we find a design example? Ant idea?

Thanks

 

[Berniedog]

Did not get article. Do not have a design example.

Bernie,

Sorry it took so long, only 3 months, but here's the article on design of stacking tubes by Safarian and Harris.
