CONSTRUCTION OF CONCRETE SILOS AND STACKING TUBES FOR STORING GRANULAR MATERIALS (ACI ) AND COMMENTARY–ACI R-. ACI January Standard Practice for Design and Construction of Concrete Silos and Stacking Tubes for Storing Granular Materials. Does anyone have experience with ACI and designing steel bins? I am specifically concerned with calculating loads on bins and the.

My designs are always either comparable or slightly conservative to him. I pretty much use the at rest pressure with the 1.
While I find the science interesting, where I end up is more important than how I get there. The Eng-Tips staff will check this out and take appropriate action. I get slighlty higher lateral pressures, but he uses slightly higher impact factors Gaylords factors.
But that’s just a guess. A newer version of this document exists. Appears on pages s: What I want is ‘good’ final answer. I can live with that.
Register now while it’s still free! Bin design with ACI What I recall from using the Gaylord book is that they give several different equations and factors, and then say “You can use this one, but some people use this one and this third method seems to work okay too”.
Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. It’s possible that many of the ‘old’ designs exist with a reduced factor of safety. He uses the Gaylord’s infomation. Red Flag This Post Please let us know here why this post is inappropriate.
I would also be cautious about using a particular approach just because it has given “good” results before. Digital Transformation may be defined 313–97 a number of different ways by analysts or enterprise software vendors. Buzek as the author. For those so inclined the Jenike and Johanson site at www.
Thanks for your comments. The point to be learned is that there is not just a wide variation in the methods used, but in the loads themselves. I think I saw this years ago and it was a good reference. Oct 1 I haven’t made it through all of it yet but plan to do so to see if they have changed any of their procedures, or if there is anything else new.
Download Now Defense manufacturing is all ack project manufacturing and project accounting. Bin design with ACI aggman, You mention that you work with someone who has been doing this for years that uses Gaylords information and is unwilling to change.
There are many other materials that can cause unusual and serious functional and loading problems, so I agree that caution is certainly warranted when designing a bin.
I have used ACI quite a bit. Students Click Here Join Us! Click Here to join Eng-Tips and talk with other members!
This should be 331-97 enough for me at least for cement, sand, and gravel where I am now working.

ACI utilizes at rest pressures larger. Defense manufacturing is all about project manufacturing and project accounting. I think I’m with you on this in terms of the K factor and overpressure of 1. It’s one of the books I had forgotten about, or at least couldn’t remember enough to be able to find it zci.
Appendices provide values for over pressure and impact factors form stored materials.

Very true about the older designs. You can make more money that way. Silos and stacking tubes are special structures, posing special problems not encountered in normal building design.
