Thanks, I have access to the book. Did not realize it addressed round shapes. Thanks

Anyone have any idea how one would determine if a steel pipe would need wall reinforcement due to the secondary moment due to a shear tab welded to the face of the pipe (instead of a thru-plate connection

Does anyone know of any good resources which address the various values (lbs/ft.) for shearwalls constructed of plywood on light gauge metal framing. I have some information from APA (American Plywood Assoc.) and some information from AISI. But the information is sketchy at best and does not...

You are right, they do publish that information, however the minimum slab above flutes is 2" in any of those design aids. I did contact them and got the same answer as SDI etc.

I have contacted SDI, ASCE, ACI etc. and no one seems to know, does anyone know of research which backs up the SDI and ASCE standard 2" of concrete above the flutes?

try "Civil Engineering Reference Maual for the PE Exam" by Lindeburg. It is about $150 but worth its weight in gold. It (and the practice exam put out by NCEES) was the only thing I studied and I passed last falls exam.

Jae, thanks for the direction, I'm looking into ISU. Also the info on what happens to a thin slab is good, now I just need some research quantifying it. Taro, good tip, but the slab is on joists and not on beams and it is only composite in itself, not in its interaction with other structural...

Does anyone know what the minimum thickness of composite metal deck is or where that might be found? The vulcraft catalog doesn't give values for slab thickness above flutes less than 2" (for 1 1/5" deck) and I don't know the reason for this. As might be expected contractor has poured...

Taro thanks for the answer, looked it up and it is exactly what I needed. As suspected my values (based on what is in the back of the green book) are too high. Not sure why the discrepancy, but I'm going to work on this awhile to figure it out.

Is anyone aware of Single angle design aids for ASD, perhaps a spreadsheet, tabulated values, etc? I am not convinced the allowable bending stress values I am coming up with are correct, they seem to high. I am calculating according to "specification for allowable stress design of...
