- Homework Statement
- Anyone here familiar with StaadPro? In the software, Moment about x axis was defined as torsional moment.. While moment about z and y axes are bending moment... Why is it ?

- Relevant Equations
- Not applicable

**The direction of x, y and a axes were shown in the highlighted part..**

I think it is wrong. For red circled beam, i kinda agree that

**Moment about x-axis was defined as torsional moment.**. While moment about z and y axes are bending moment...

But for blue circled beam, I think that

**Moment about z**axis was defined as

**torsional moment.**. While moment about x and y axes are bending moment...

Please correct me if I am wrong.
