I think I may have not been clear. I am looking to find the Ic of the weld lines for the structure of this shape. So Ic will be in units of length^3 not length^4. RobyengIT had a good resource, I was looking at case 23 (see photo below) and I had a question. Would the Ic be greater in the left...

I have been doing weld design per Blodgett's "Design of Welded Structures" and I had a question regarding how to find the Section modulus of the example on page 7.4-14 that involves a pole with a base plate and 4 gusset plates. I looked at my shear and moment acting in the x-axis or y-axis so...

Thanks for the response! Is there any way you can show me some resources that back up what you said? I will have to explain to my boss my reasoning for loading it with a triangular distribution with the max at the "free" end. Thanks

I'm not looking at the design of an entire screw anchor. I am just looking to design the thickness of the helical plate really. We have a spreadsheet at my work, but we believe that the check for the helical plate is too conservative.

I am looking for resources regarding or relevant to the design of a helical plate that is attached to a screw anchor for foundations. Thank you in advance for any help.

I am working on a concept for design of a helical anchor plate. I have come up with a process that I need to try and make more efficient. My question is how would you apply the soil resistance to what is essentially looked at as a cantilever beam (unit section of the plate)? Is the resistance...
