Truss Connection Details
Truss Connection Details
(OP)
I try to design a steel truss connection using gusset plate welded to truss chord. The diagonal tension member and vertical compression member will be welded to gusset plate. Please see attached sketch Detail Option 1. I am thinking to extend the vertical member to the face of chord and also weld vertical member flanges to the chord. Are these two details provided same gusset plate design? Does the detail option 2 make the connection stronger than the detail option 1? Thank you very much.






RE: Truss Connection Details
But if correctly designed, Option 1 will work just fine. And it will be much easier to build. The vertical doesn't have to be cut exactly to the right length or perfectly square. If you look at 100 trusses, something closer to Option 1 will be on 99 of them.

Why aren't the 2 Channels back to back being bolted? Why is the vertical member a wide flange and not a 2C's or 2WTs?
Depending on your true clearances, welding the web of the W4 on the side where you have the diagonal could be difficult.

Since the vertical member carries compression only, you could rotate the vertical 90 degrees and rely on direct bearing between webs of the vertical and chord (assuming the bearing area is adequate for the compressive load). Then the weld would be nominal unless there is a possibility of stress reversal.

does detail 1 look particularly "tender" for bending about the weak axis of the gusset ? is shoring during erection a reasonable assumption ?
detail 2 looks like it requires the compression member to be cut very carefully (presumably you'd use the same gusset at the other end).

I would suggest in either option adding full height stiffeners
