Usually you would add some vibration damping device or helical strakes to address the vortex shedding, otherwise if you increase the thickness to handle the vortex shedding loads then ets will end up with a very thick stack.

The significant discrepancy between the two approaches is explained by the very high overturning force at the top of the stack given by the static procedure, as a result of the very high mass of the supporting structure.

Found this in Gaylord and Gaylord, edition. In reviewing the issue, compression was never the problem Gaylord’s Eqs return similar results In hindsight Or, as paddington suggested any discussions of the standards in journals, prior to adoption. I think you’re ssme the right track now. I still think this would be a real st question to ask ASME. National Fire Protection Association. What do the power transmission people do with their towers? Notice the reference and similarities to the ASME.

Your back-asswards thoughts are exactly what the senior structural guys i talked to thought, but reversing the signs would make less sense as it would be setting a required minimum thickness of mm Also, see attache Gaylord and Gaylord Steel Stacks. Download a few pages of that so I can see what they asme sts 1 2011 doing, and what their formulas and load cases look like.


Join your peers on the Internet’s largest technical engineering professional community. And, to wonder whether in some cases you should add an amplification factor or work at a lower stress to account for low cycle fatigue.

A more interesting question now may be to read some of the literature on vibration and dynamics of stacks. Artificial intelligence AI has recently become a field in which research is proceeding at a feverish pace. I have never seen a situation where thickening a plate made a buckling problem worse, at a given stress level, unless it changes the buckling from one mode to asme sts 1 2011, and their cases are based on the former.

Design of stacks Aliaga: Before i can debate which method is acceptable i have to understand why on Earth the ASME would be limiting thickness based on D in steel stacks.

Asme sts 1 2011 far as it being a misprint, i have, and an earlier version at my office and they all state the same exact formula. There should have been discussion of the standard in their proceedings before it was adopted, and there might well be a code case on this very question. Can anyone comment in agreement or disagreement with the above methodology?

In this case, at mm D, a thickness of I have a couple of ideas but they are no more than speculation, however, do check with ASME. Ill take a look at them tomorrow.

Insulation and linings affect total heat loss. Keep in mind, this equation has no relation to loads, height, wind, eq, ect. Size px x x x x I’m asme sts 1 2011 sure why the thickness is so high mm. Alternatively, t must increase if you want to work at a higher buckling stress, still less than. Thus the large difference in empirical approaches, different guy’s best guesses. Resources Digital transformation may be the most frequently misunderstood and misused term in business discourse today. Please help us to share our service with your friends.


Having this aspect into consideration, static equivalent forces were calculated asme sts 1 2011 to defined in the ASME-STS code, in order to check the amplitudes of vibration and stresses.

A minimum of 8 tt Now I have to stop and asne chap. You say your own calcs. The stack in question is outside of our “normal design” in being so tall and slender, but i have a hard time asme sts 1 2011 going with our forign design while not understanding this ASME stipulation.

They talk about out-of-roundness of 1 or 20111, and very small differences in edge or lateral loading as having large differences in buckling strength. Ihe Iow ambient temperature expected should 1.

I could take about months to get an official response. My head is spinning. Do a little rearranging, add a few fudge factors and you might get near ASME’s eq.

I sent an email and will update the thread with any response. He’s probably the most knowledgable guy with regard to stack design. They are as follows Case 4. As you go to thinner plate, the allowable stress equations will start needing to consider asme sts 1 2011 buckling. It’s easy to join and it’s free. Asmme company desings and has designed steel stacks by the above 4 cases for years.

ssts We are starting to have some real concerns with our international designs that do not address this issue. Can anyone offer any advice or interpretation?

Im my calcs it is.
