Primary Torsional Moment Mt,pri on Cantilever Beam with Warping Restraint

Primary torsional moment Mt,pri on an I-section restrained on one side with warping restraint in RFEM 6

Distribution of the primary torsional moment Mt,pri on an I-section restrained on one side under a torsional moment of 10 kNm. Mt,pri is 9.16 kNm at the free end and decreases toward the support to 0, since warping is restrained there.
