I = area moment of inertia of ring cross section about the principal axis perpendicular to the plane of the ring (length4). [Note that for a pipe or cylinder, a representative segment of unit axial length may be used by replacing EI by Et3 / 12 (1 - v2 ) e ≈ I / ( R A) ...
An alternate procedure is suggested by Blodgett in Design of Welded Structures for substituting a torsional resistance factor, Rt, for the polar moment of inertia in the equation for stress. The torsional resistance factor, Rt, is determined by dividing up the composite section into its component ...
