Handling Torsion Due to Thermal Loads
Handling Torsion Due to Thermal Loads
(OP)
Does anyone have any good resources on designing pipe supports as anchor points in hot run of pipe? The sketch I have attached is something I've heard works for redirecting the torsion created from the pipe's expansion and the offset of the pipe center line and center of the wide flange beam. I've been told that the channel is much stiffer from a load in the indicated direction and will help reduce torsional forces the wide flange sees during thermal expansion/contraction. Any guidance would be appreciated.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Also because I plan on having the channel take the expansion load do I have to account for any load acting on the WF? Would you estimate that from a stiffness ratio between the two members, channel in strong axis bending the WF in weak axis bending?

Another, horizontal clip angle would be the way to go.
That's what I'd do if it is indeed a thermal load and not an imposed thermal displacement.

This is the same effect that I'm worried about as well.

I have not designed many pipe supports, but since the point you are considering is fixed, all thermal expansion forces in the pipe line will be resisted by the C10 channel. That is, assuming the C10 has adequate end connections and the span is short enough that its deflection is not significant. The W8 is just there to hold up the C10.
