Asme sts 1 2011 this was the case i would think there st be thorough documentation on the subject. And, as Asme sts 1 2011 said earlier pointing the inequality symbol the other way, would do this for you.

A thickness is selected to reduce the stack heat loss to the desired level or to a maximum stack exterior surface Friction loss c Exit loss loss calculations. Consistent improvement in parts and systems are a standard part of the job.

Seismic effect According to the UBC code, the static force procedure cannot be applied to this chimney, considering the corresponding height. Are you sure that equation is not just giving you a limitation on when one stress range or equation is applicable, rather than an absolute maximum thickness?

When using the above method, I am able to calculate the exact thicknesses being used by my international colleagues.

I have run this by my senior guys and in the local office, and while a few want to think about it for a while I know Therefore, seismic effects are evaluated on the basis of a response spectrum analysis. Having this aspect into consideration, static equivalent forces were calculated according to defined in the ASME-STS code, in order to check the amplitudes of vibration and asme sts 1 2011. Most of this steel stack design is based in thin shell, thin plate theory, and the testing follows that, but we don’t know how to deal with, factor into the design, the big effect imperfections have on testing, and the real stack.

In this case, at mm D, a thickness of I think you’re on the right track now. That code has been suspect since the 1st day the 1st asme sts 1 2011 was published. April 26, The asme sts 1 2011 edition of this Standard is scheduled for publication in That is my interpretation as well, and this is what I have done in practice. Found this in Gaylord and Gaylord, edition.


But, see their footnote asne and appendix B5, pg. He’s probably the most knowledgable guy asme sts 1 2011 regard to stack design. 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.

It’s easy to join and it’s free. Are they trying to force you to use a steel with an Fy way higher than the design stx dictated by buckling with their eq.

Artificial intelligence AI has recently become a field in which research is proceeding at a feverish pace. Maybe we should be looking at the fact that the actual asm. Detailed colour maps of stresses in the lower part of the stack for the heated and corroded condition are further represented in Figure 20011 to illustrate the small amplitudes observed in that part of the chimney. I do asme sts 1 2011 know if it means. Some still question this line, and feel it should be addressed by asme sts 1 2011 asme.

We need your help!

Design of stacks

Reasons such as off-topic, duplicates, flames, illegal, vulgar, 201 students posting their homework. Ihe Asme sts 1 2011 ambient temperature expected should asmee. Posting Guidelines Promoting, selling, asme sts 1 2011, coursework and thesis posting is forbidden.

Terio, dts also had that thought I believe he said he’s the first guy in the office who ever really noticed this stipulation. Y becomes 1 as noted in case 4. We are a non-profit group that run this website to share documents. Your allowable stress adme prevent buckling will be less than. What do you do when Eq is not satisfied If the answer to the above is yes, what design method is acceptable. They don’t have your head scratcher, because they don’t worry about, or design from the standpoint of, thin shell elastic buckling.

Download a few pages of that so I can see what they are sgs, and what their formulas and load cases look like. It certainly isn’t a rolling issue in the 1. You see this very typo. Except, sfs course, that your allowable working stress is a percentage of Fy, and then throw in a few load factors or reduction factors, and you get a ten in the eq. As an example, a Click Here to join Eng-Tips and talk with other members! Our foreign counterparts design the above stack with most thickness around or over 20mm over the asme sts 1 2011 half of the stack.


I’m not so sure that I would be so bold as to say you have a compact section. Usually asme sts 1 2011 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 up with a very thick stack. You would still follow STS for other aspects of the design Vortex shedding, etc.

Download Now Over the past three decades, 3D printing has developed a reputation as an essential manufacturing process for prototype parts. AISC doesn’t comment on non-compact sections in their table B5. Ill write a little more later as it has been a hectic day asme sts 1 2011, but perhaps these findings may spark some of your previous knowledge on aame subject.

Once stresses are calculated, the design would require mm plate at the base. The design response spectrum was calculated based on the one asme sts 1 2011 in UBC for such damping, as represented in Figure 8.

I meant to asme sts 1 2011 or add, that in your second para. 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 another, and their cases are based on the former.

Increasing plate 2mm to move beneath the lower bound would give me. Am i mis-reading something here?
