WT shapes for vertical bracing

[john.lauer]

Has anyone tried to do bracing with a WT shape? This is the second time I have had to do this and the Brace tool doesn't seem to work well for me. I cannot offset the the brace so that it is back to back with another WT brace. I wind up using the beam tool and changing the start and end elevations. Since I cannot convince the engineers to use tube steel, this is the only way I can get it to work. Is this lame? I have little experience with Revit, by the way.....
Thanks for any advice.

I don't have allot of experience with this yet either, but I just tried something I think may work for you.

Create your WT brace and place it at the levels/elevations as required. Then copy it, and rotate the copied one (Cross Section Rotation = 180) so they are back to back and move it on to the original one. You may need to tweak the start and end extensions for each one to line up.

Hope that helps.

Thanks, I'll give it a try. What I have been doing is working (sortof), but I think that this is something that Revit needs to fix because this type of bracing is commonly used. Whatever, that's just my opinion...
Thanks again.

You're welcome.

I would imagine that "double angle" bracing would pose the same problem huh? Very often we use double angle bracing where you would need two members attached together similar to your (2) WT's correct?

Like I said, I don't have allot of experience in this yet either, I've been doing mostly concrete work. Maybe someone with more knowledge can chime in and let us both know how this is normally done or that it is a known issue.

The out-of-box families do not work for most bracing, unless the bracing member is symmetrical.
Tubes, pipes and WF work OK. also the Double angle family works.
But single angles and WT's do not work.
But single angles and WT's can work if the family is revised for bracing, so that the bracing members center reference plane works with the analytical layout of the bracing.
I have seen revised families for single angles, but have not seen one for WT's, but maybe someone has made a WT family for bracing, and they will share...?
Yes, I agree a few more things need to be revised in Revit for placing bracing.

Thanks for that info and the .rfa file. I'll try to look into creating a WT brace family, but I wouldn't hold your breath for that 'cause I'm not the best family man...but I try.
Thanks again.

Try this WT Brace Family, I have not done too much testing.
You can set gap or space for offset to gusset connection plate.
The Analytical layout is on the gridline center so you can layout bracing in framing elevation ref plane.
You will need to set framing elevation view far clip offset, if you use a larger tee, or you will not be able to
see the larger tee in the framing elevation.
