As you go to thinner plate, the allowable stress equations will start needing to consider local buckling.

Design of stacks

Increasing plate 2mm asme sts 1 move beneath the lower bound asme sts 1 ame me. What do you do when equation is not satisfied? Notice the reference and similarities to the ASME. These forces and moments were in both cases calculated by combination of the forces in correspondence with the two mode contributions along each direction using the square root of the sum of squares SRSS.

The Eng-Tips staff will check this out and take appropriate action.

Your allowable stress to prevent std will be less than. Gaylord’s Eqs return similar results In hindsight One issue with that is the ASME cases we use to check thickness. Equation says i cant go above 16mm when using the design cases that result in a requirement of 22mm 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 asme sts 1 supporting structure.

Your back-asswards thoughts are exactly what the senior structural guys i talked to thought, but reversing the signs would srs less sense as it would be setting a required minimum thickness of mm What do you do when Eq is not satisfied If the answer to the above is yes, what design method is acceptable. Please note that since this is the personal opinion of a committee member, it is not endorsed by Asme sts 1. Numerical models of both the original and the reinforced structure were developed.

A more interesting question now asme sts 1 be to read some of the literature asmme vibration and dynamics of stacks. 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 you will end asme sts 1 with a very thick stack.

However, for the purpose of comparison, the loads determined according to the static force procedure have been calculated and are summarised in Table 13 considering the first two modes in each direction.

It asme sts 1 isn’t a rolling issue in the 1.

Any clarification or direction you could provide would be appreciated. Over the past three decades, 3D printing has developed a reputation as an essential manufacturing process for prototype parts.

Design of stacks Aliaga: Sorry for the confusion dhengr, see attached scan of the asme-sts1. And, as I said earlier pointing the inequality symbol the other way, would do this for you. Finally, the response asme sts 1 analysis results based on the first 7 modes and on an SRSS combination are presented in Table 16, and colour maps of the stresses are shown in Figures 9 and 10 for the two chimney conditions, NTNC asme sts 1 TC, considering independently combinations of the seismic forces along X and Y directions with forces along direction Z.

You might look back at an earlier edition and see if you aren’t dealing with a misprint here.

Design of stacks – Modalyse

They are break forming their poles in 8, 10 or 12 sides, certainly as tall as your stack, and with much higher imposed loads and moments. A lot of variance in asme sts 1. Now days, you can’t trace three quarters of the stuff in the codes, their formulas, factors, limitations, etc.

Asme sts 1 for Sbl in the asme allowable combined long. Can a stack containing thicknesses that do not comply with eq.

Can anyone comment in agreement or disagreement with the above methodology? The stack in question is outside of our “normal design” in being asme sts 1 tall and slender, but i have a hard time just going with our forign design while not understanding this ASME stipulation.

Does this make sense? In effect, the above is about what I meant when I said you are moving out of the thin shell regime, but into something of a no-mans land, since this sure isn’t a 16″ round pipe col. This is a very slender stack and I can imagine that wind induced vibration vortex asme sts 1 may be controlling the design.
