I have used ACI quite a bit. I get the impression when reading the Gaylord text that the value of K is sometimes used as a fudge factor to skew results towards where the researchers want to end up anyways. An older version of the spec ACI had factors up to 2. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I get slighlty higher lateral pressures, avi he uses slightly higher impact factors Gaylords factors.

JStephen Mechanical 9 May 05 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". The point to be learned is that there is not just a wide variation in the methods used, but in the loads themselves. I would also be cautious about using a particular approach just because it has given "good" results before. You could go on for years building structures that were seriously overstressed, until finally one collapses.
Based on test results shown in Gaylord the ACI equations are as good as any and it is an actual written specification. For hoppers both the Jenike and Walker equations are probably satisfactory. This should be good enough for me at least for cement, sand, and gravel where I am now working. 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.
So be it. You can make more money that way. For those so inclined the Jenike and Johanson site at www. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Cancel Thank you for helping keep Eng-Tips Forums free from inappropriate posts.
