I have a question regarding the calculation of torsion in curved beam. I have a curved beam with a couple of supports. When i apply a vertical load, the My - moment distribution is what i expected.
When i add a torsion moment load (Mx) the My - moment distribution changes.
I suspect that this is caused by the ‘Bi-moment’ effect, is that correct? Or is there a different effect causing this moment?
Thank you in advance
