Arc Spot Weld and Puddle Weld Capacity 3

[keen_mentee]

Hi All,

I am analyzing a metal decking over OWSJ for higher wind uplift. The decks are attached to the supporting OWSJ with 5/8" puddle weld. In the past, I looked at few reports I found online and used the lowest capacity and they worked for my project. However, now I am working on a project that has a higher demand on the puddle weld. How can I calculate the puddle weld capacity for a 22 GA. metal deck? I skimmed through AWS D1.1 but could not find anything. Any suggestions?

Thank you.

The metal deck would be governed by AISI, check AISI S100 Link

This would be in one of the AISI codes. AISI-S100 I believe. Chapter J.

But, to make your life easier: [URL unfurl="true"]https://vulcraft.com/Verco/SteelDeckUniformLoad[/url]

At the top you can select report tabs, go to "connections" and scroll to the bottom for the weld capacity calculations.

You can also look in AWS. But metal deck isn't structural steel so D1.1 won't help. You need D1.3, sheet steel.

The perimeter of the slot/hole multiplied by the thickness of the decking will give you the shear area (this is an approximation). With your uplift assumptions, you can determine shear stress. For design strength, assume fillet. This is assuming shear perpendicular to the plane of the decking.

I would look at AISC for guidance.

This is covered specifically by AISI codes, not AISC.

CSA S136, which is part of the AISI group for CFS construction has this. This is from an older code; I don't have the most recent code for this. They also show the calculations to determine shear stress capacity:

Dold, thank you for your correction.
