Applying torque/moment to a buckling analysis

Applying torque/moment to a buckling analysis

Applying torque/moment to a buckling analysis

(OP)
I need to perform a buckling analysis on a weldment at my job. There is a leg that swings, much like a clock pendulum, between two plates. We have created an I-beam type weldment to mount this leg.

In all my reading, it seems buckling is determined based on a single force. This set-up leads me to want to use a torque/moment applied at the pinning point. Is that valid?

Why do you have to be a nonconformist like everybody else?

RE: Applying torque/moment to a buckling analysis

Yes, combined load buckling is a valid concern, you can read up on buckling from off-center loads (moment and force combinations), Roark's Formulas For Stress and Strain has quite a bit of information on this in the Elastic Stability section. Whether your "pinning point" can transmit a torque is another question that you haven't given enough detail for us to answer. A sketch might help.
