You're welcome.

I'm glad you found the explanation to be clear since there's a lot of steps to determining all of the weld stresses, especially when it comes to the Instantaneous Center of Rotation Method.

Thank you so much for the kind words!

Thank you so much! Many more videos are planned and are being worked on right now.

@@StructuralCentral Please do some seismic load on structure!

Thanks for the suggestion. It definitely helps to know what topics people are interested in.

Thanks! I'm glad you think so.

That's the plan!

I don't see anything about the methodology that would preclude you from using it with welds that have different leg sizes. The formulas for Δu, Δm, and R all include "w" so you would just use the applicable fillet weld leg size there. I don't know if testing has ever been performed on weld groups consisting of welds with different leg sizes to confirm that the method is still applicable, though.
