D14.C.6.4 Torsional or Torsional-Flexural Buckling
Per section 13.3.2, the factored compressive resistance, Cr , of asymmetric, singly symmetric, and cruciform or other bisymmetric sections not covered under 13.3.1 shall be computed using the expressions given in 13.3.1 with a value of n = 1.34 and the value of fe taken as lesser of Fex and Feyz for single symmetric section, with the y axis taken as the axis of symmetry.
