Composite Beam Shear Transfer through edge angle 1

[rgerk]

I'm working on a project now where the welding inspector told us that attaching the shear studs to an edge angle isn't allowed. The perimeter beam has a six in flange and the edge angle is a L6x6x5/16. The angle totally covers the beam flange and is butt welded on each side. It's an awkward area, but the inspector is saying the shear studs must attach directly to the beam flange and not the edge angle.

Has anyone heard of this requirement? Seems to me that if the stitch weld between the angle and beam can transfer the shear from the stud to the beam, what's the big deal?

Any thoughts.

Thanks.

My 2 cents:

(Assuming this situation is in the US) Paragraph I4 of 9th Edition Steel Manual does state ' ....shear connectors welded to the top flange of the beam...'.

Therefore, I do think think the inspector has a point.

Though I cannot think of a reason why it would not work as long as the weld between the angle and the beam can transfer the horizontal shear between the two elements, I think this is a situation best avoided. FWIW, I always set the toe of angles or bent plates continously connected along the top flange of a beam to recieve composite studs at least 1" away from the centerline.

JMHO

Classic cook-book inspector finding....i.e., "it's not in the book so it is wrong".

Just tell the inspector that your 6x6x5/16 angle is actually the load carrying memeber and workign in composiite wit the concrete and you don't even need the wideflange below. He'll probably bless it as he surely knows nothing.

You are the engineer. You should be able to determine whether you can weld the studs to the angle.

If it is OK then tell the inspector that you determined that it will work.
