Steel Retrofit - Fully Welded Splice
Steel Retrofit - Fully Welded Splice
(OP)
I have a welder requesting to splice a T Retrofit to the bottom of an existing wide flange beam. They are concerned they won't be able to get the T Retrofit into place without cutting it. They said that another structural engineer provided a detail for some previous retrofit work they had done on another job. The detail shows the T-beam being cut at a 45 degree angle through the depth of the beam. The flange would then be prepped on an angle to get a full-depth weld to attach the entire section. Then on the web of the beam they attached a "fish" plate that is welded on the longitudinal edges, but specifically details that the tranverse edges not be welded. Is this a typical detail for a beam splice? I have not come across anything like this, but in my mind, as long as the pieces are fully-welded, this should transfer the flexure loading through the beam.
Any reference or discussion would be appreciated.
Thanks!

I would use a plate instead of a full pen weld on the WT flange. Whenever a contractor asks to do the full pen weld I offer them the choice of doing the full pen weld and getting it UT tested, or doing the flange splice plate with fillet welds. They always seem to go with the later after I bring up UT testing.
If the shear load is low there isn't mush load on the web plate

I have not seen such a splice yet either.
