The present paper deals with warping torsion, bending and axial forces. Presenting a method to compute the shear center of the effective section, the warping constant and warping coordinates needed to compute the stresses due to the bimoment. The stresses are compared between stresses in the gross and effective section when a Bimoment only is applied for the sake of simplicity but any combination with axial and biaxial bending moment is allowed. This paper fills the gap of the current codes to deal with bimoment in Class 4 sections.
