I think you have to exclude first the weld region, as stresses there would be considered peak. Then near the weld you will consider stresses as local.
I don't think having a defined distance of local membrane is useful, i think it is best to ask your friend engineering judgement here
I agree but for specific geometries like the nozzle/header assembly of my previous post subjected to external loads, i think it will be difficult with just an hand calc
Hi,
I'm looking for some advice on the new buckling analysis methods of ASME VIII Div 2 edition 2023. I am currently designing a tangential nozzle/header assembly that is subjected to external pressure.
Method A is "intended for use on independant component", so my choice was to go for...
Very insightfull TGS4, thank you for the explanation. I'm not familiar with SIF calculation as per Section VIII Div2. In my work for SIFs calculations we only use B31.3 and B31J, which appear to be simplified compared to section VIII Div 2. Stress range calculated with B31.3 is straightforward...
In table 1.1, 2.3, if you look at the schema there is a radius r2 for the insert nozzle. Under it there is a direct reference to note 8, which is not the case for the set-in nozzle. That's why i though this note was only for insert nozzle, but i think you're right it is more general than that...
You can have a look at note (8) of B31J. Looks like from the first sentence that insert are better for SIF, since you automatically multiply them by 0.7.
I'm not familiar with designing foundation, but if you consider that the lug are pinned to the ground, then you consider that moments wont be transfered at all to the foundation and will only be sustained by the beams/lugs. In this configuration i don't see why you should design foundation to...
