Minimum Return Distance on Fillet Welds
Minimum Return Distance on Fillet Welds
(OP)
All,
What is the minimum return distance for a typical fillet weld?
To set up my exact detail:
-I have precast hollow core bearing on a concrete foundation wall
-The precast will have steel plates embedded in the bottom
-We will bolt a flat steel plate to the inside face of the foundation wall
-Fillet weld where the two steel surfaces meet
Is there a minimum distance by code that our embed plate needs on the flat steel plate?
My gut tells me a minimum of 1/2".
There are also a great deal of lateral loads due to soil pressures (hence why the welded connection is necessary).
Any reference or knowledge would be greatly appreciated.
Thanks,
jReck

Dik: There are some cases where we are taking 2200 PLF adjacent to hollow core forces and 1900 PLF parallel with the hollow core forces (both lateral earth forces). These loads can act simultaneously. I was needing one of our larger 7x7 embed plates with 4 studs @ 18" O.C. to make these loads work. Did you have a different idea in mind Dik? I do not believe drilled pins will be able to withstand these forces.
