Sizing and Manufacturing of Unique Joist Hanger

[Bråkis]

Is the steel beam calculated to withstand the load and the torsional moment that the glulam beam will introduce at a point? Since the OP says it's already in place. It might be dimensioned for a completely different load case?

It is calculated to handle the load, yes, (we are removing more load through the renovation than we are adding) but we want to avoid torsional moments as much as possible. Therefore, I would prefer not to have the glulam beam resting on the flange of the I-beam.

You don't weld brackets, period. Make a drawing and have someone water cut and bend it. 6mm thickness is a reasonable dimension for this solution. Fill the beam with full-height sheet metal, but don't place the holes too close to the edge of the beam.

I have talked to laser cutters in Småland and they find it a bit tricky to bend twice since it's so narrow between the halves (66mm) that it's better to make two identical halves and then overlap the bottom and weld.

Good point. I'll proceed with 6mm.
