0017 - Axial-torsional buckling under axial force.

A simply supported column with symmetric section (+ and I) buckles in torsion under the action of an axial load.

Torsional buckling under axial force is a constitutive phenomenon in the context of intrinsic frame theories.

Double Symmetry  

The critical buckling load for the torsional buckling of column subjected to axial compression is given by $[15,16]$ :

where $r_2^2=\left(I_y + I_z\right) / A + y_0^2 + z_0^2$ . Using the properties from Table 1 , the elastic torsional buckling
