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.

You can make more money that way. For those so inclined the Jenike and Johanson site at www.

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”. 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.

The standard includes requirements for seismic design and hopper bottom design. Register now while it’s still free! The standard includes requirements for seismic design and hopper bottom design.

But that’s just a guess. zci

For hoppers both the Jenike and Walker equations are probably satisfactory.

What I want is ‘good’ final answer. It seems to work out fairly close. You could go on for years building structures that were seriously overstressed, until finally one collapses. Oct 1 While I find the science interesting, where I end up is more important than how I get there.

An older version of the spec ACI had factors up to 2. I get the impression when reading the Gaylord text that the value of K is sometimes used as a fudge factor to skew acci towards where the researchers want to end up anyways. ACI utilizes at rest pressures larger. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

I get slighlty higher lateral pressures, but he uses slightly higher impact factors Gaylords factors. Click Here to join Eng-Tips and talk with other members!

Prior to that the people I knew were using equations published by Ketchum about a hundred years ago based on Janssen’s work. The Eng-Tips staff will check this out and take appropriate action. This ACI standard practice gives material, design, and construction requirements for concrete silos, stave 331-97, and stacking tubes for storing granular materials, It 3139-7 design and construction recommendations for cast-in-place or precast and conventionally reinforced or post-tensioned silos.

If there are any suggestions or if anyone knowns of a source of good information, please let me know. This section specifies the overpressure factor to be a 331-97 of 1. Gaylord, and I believe the old ACI calculated the lateral pressures based on active pressures with the charted overpressure coeficients.

Buzek as the author. A newer version of this document exists. I think I saw this years ago and aic was a good reference.

I pretty much use the at rest pressure with the 1. It’s one avi the books I had forgotten about, or at least couldn’t remember enough to be able to find it again. This document was replaced by
