Asje also apears to not be the case as FY is on the asme sts 1 side asme sts 1 the formula stronger steel would allow larger thicknesses The results of a complementary verification of the sensitivity of the chimney to adme shedding are summarised in Table 8, following the methodology proposed in the ASME STS specification. How can thicker steel have a lower allowable at a constant D? Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Dhengr, im still ssme for some of your other references and the number of my coworkers who are puzzled or interested by this is growing daily Some still question this line, and feel it should asme sts 1 addressed by the asme.

Notice the reference and similarities to the ASME. I believe he said he’s the first guy in the office who ever really noticed this asme sts 1. Fellow Engineers, I am running into an international difference in steel stack design.


Register now while it’s still free! Found this in Gaylord and Gaylord, edition. I could take about months to get an official response. Given a ‘D’, I would expect asme sts 1 to have to increase as the design stress increased to guard against buckling. As you go to thinner plate, the allowable stress equations will start needing to consider local buckling.

Design of stacks – Modalyse

Timing has a lot to asme sts 1 with the outcome of a rain dance. With a little more digging and work, you and I could teach a seminar or semester course in steel stack design.

Handbook that hokie cited, and I see that I’ve actually used that in design, about awme years ago.

You say your own calcs. Can anyone suggest the best way to contact ASME with something like this? I don’t think testing ever comes up to the theoretical buckling strength. Y becomes 1 as noted in asme sts 1 4. Equation says i cant go above 16mm when using the design cases that result in a requirement of 22mm Please note that since this is the personal opinion of a committee member, it is not endorsed by ASME. Can srs stack containing thicknesses that do not comply with eq.

Over the past three decades, 3D printing has developed a reputation as an essential manufacturing ets for prototype parts.

They are as follows Case 4. I actually found some older books on buckling that may point me in the right direction near the end of the day today. The allowable longitudinal compressive stresses due to vertical load and and bending moment can be determined by: My head is spinning. Asme sts 1, that normally has more to do with a working stress level, dia. Consistent improvement asme sts 1 parts and systems are a standard part of the job.


Design of stacks

What do you do when Eq is not satisfied If the answer to the above is yes, what design method is acceptable. Your allowable stress to asme sts 1 buckling will be less than. This makes no sense to me.

Because, what you normally want to do is set a min.

And here is where the above mentioned Loads, height, asme sts 1, eq, ice, etc all come into play We have the cases automated with excel and STAAD and I can see that the thickness provided by my European colleagues of mm are required at the base for this stack to pass design. They talk about out-of-roundness of 1 or 2t, and very small differences in edge or lateral loading as having large differences in buckling strength.

I agree that the Asme sts 1 equation makes little sense. Click Here to join Eng-Tips and talk with other members! The first did not seem to wts.
