Ductwork design
(OP)
Can anyone recommend a good reference for the structural design of large industrial ductwork?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Ductwork design
They have complete designs & details of ducting. There is one publication for circular ducts & another one for rectangular ducts.
I have designed some 2 m dia SS ducting using their recommendations. The saddle support design does not include saddle tip stresses (as detailed in Rouke & Young, formulas for stress & strain, AWWA M11 for steel pipelines, etc) but this is compensated for by the use of lower stresses. I don't think that this degree of detail (saddle tip stresses) for duct supported on saddles is warranted.
The SMACNA publication has been around for a long time (before 1975 I think) so obviously there is a continued use & successful experience behind it.

Ductwork is a broad word. If you are looking for light hvac type then the previous posts are probably a better fit. If you are looking at stiffened plate steel construction as in boiler breeching etc. for industrial applications you can look at Design of Weldments or Design of Welded Structures by Lincoln. If memory serves me both books have the section of stiffened plate steel construction. Ive used these texts for breeching applications.

This provides a good overview of the design requirements but it is not a governing code.
