Beam to (Sloped) beam connection

Beam to (Sloped) beam connection

Beam to (Sloped) beam connection

(OP)
I have attached a 'sketch' of a secondary I-beam connected to the web of a top chord node in a truss.
n.b top chord made up of two C sections back to back with 12mm gusset in between.

Anyone familiar with this connection, would you recommend the fin plate configuration as in the diagram?

Wouldn't that induce a rotation of the upper chord member since it is not symmetrical?

Tnks , regards

RE: Beam to (Sloped) beam connection

That looks like a break in slope at the truss.

Normally we run beams and purlins above the support for the continuity of line, sometimes in a cantilever span configuration (there is a name for this that I never can remember).

You only introduce torsion on the top chord if the reactions are different. You could reduce this by welding, or friction bolting, tees to the end of the beam and bolting through the tee flanges and the chord.

RE: Beam to (Sloped) beam connection

(OP)
The reactions are equal, except for the edge trusses, where I have a secondary beam on one side, but not the other. So, I am assuming that the suggested solution with the Tee, can be a possible solution, right?

I was not that worried about the continuity of the slope, since I have the top flanges aligned,
and purlins lying on the secondary beam (such that the horizontal top flange of the chords wont effect the continuity).

Thankyou paddingtongreen.
