Mid-Height Bearing Floor Truss Tutorial

Recommended Posts

Has anyone here modeled a mid-height bearing floor truss in Chief?

 

I’ve attached a sketch for clarity. The truss is 24" total height, with:
14.5" bearing portion at the top (this sits on the sill)  
9.5" portion below the bearing  

 

So this is not a typical top chord bearing truss. The bearing occurs mid-height within the truss depth.

 

These are first floor trusses over a basement.

 

I’m specifically trying to understand how to model the bearing condition correctly using structure and framing settings so sections, elevations, and framing reflect this accurately.

 

If anyone has done this, could you walk me through the correct setup?

I have done those. You will need to put the first truss in, open that truss and manually modify it, then multi-copy and adjust as needed. It's tedious, but can be done, just not really automatically. You need a "dropped" ceiling for the first floor, and the 14.5" "floor framing" and you will have the heights you want.

 

Now, having said that, someone will have a tricky workaround to make Chief do it, but is the juice worth the squeeze to spend a bunch of time on? I set all my heights and simply worked through all the design development with the client before doing the trusses. No need to do it until the end or you have to keep doing it when revisions come along.
