We have investigated into the torsional rigidity of spot-welded box section beam and reported on the torsional rigidities of double and single hat beams, the warping of which is restrained at both ends perfectly, using warping torsion theory of spot-welded box section beam we have proposed. In this paper, as a further analysis, we report on following three cases, 1) A case where the warping is restrained elastically at both ends. 2) A case where torsional moment varies longitudinally. 3) A case where pitch of spot-welds varies longitudinally.
