Weld Symbol For Rebar to WF Column
Weld Symbol For Rebar to WF Column
(OP)
Thank you all for taking the time to read this.
I have a question about welding rebar to the flanges of a wide flange column. The design called out a flare beveled groove weld, see attached. We used this weld where it applies, where the rebar is parallel to the flange. However, where the rebar is perpendicular to the flange this weld is not possible. We used a ½”filet weld-all around at this location. The Project Engineer was looking for a Full Penetration Weld to be applied here. Does the ½” Fillet Weld bring the rebar to full strength and thus satisfy this requirement?
Thanks in advance.

Also says grade beam is 'embedded in mat slab', so maybe there's liquefaction issues and the grade beam is acting as a chord and the reinforcement is intended to transfer the chord force at the ends into the moment frame column to then transfer into the pad footing? Would question how the pad footing is working with liquefaction though.
I too am curious as to what welding the reinforcement to the moment frame column is attempting to accomplish here.

If you must weld bars to the column flanges, an all around fillet weld is acceptable but is difficult to do with bars in close proximity to each other. I prefer a simple V-groove facing up so that all welding is down-hand.

Some of your details are difficult to construct, and I assume the rebar are dowels only to be lapspliced with other rebar.

If I saw that weld symbol on the rebar, I would think the engineer was intending for the rebar to be cut at the ends (like a curved chisel cut) to form the flared bevel weld - a full pen weld on the rebar.

As for the welds, where the bar butts the steel, a full penetration bevel is appropriate, and a fillet weld is not as good. Where it lies alongside the flange, it would be a fillet weld, just a shaped one.
