Are they trying to force asme sts xts use a steel with an Fy way asme sts than the design stresses dictated by buckling with their eq.
Asme sts, does this thought and design process, when eq is not satisfied, coincide with the intended design of the ASME? I feel like i have to be missing something here! You would still follow STS asme sts other aspects of the design Vortex shedding, etc. We are a non-profit group that run this website to share documents.
There should have sts discussion of the standard in their proceedings before it was adopted, and there might well be a code case on this very question. Thanks and BR -Hoots P. Before i can debate which method is acceptable i have to understand why on Earth the ASME would be limiting thickness asme sts on D in steel stacks. Because, what you normally want to do is set a min.
