Torsion Rotation Formulas - Open Versus Closed Shapes
Torsion Rotation Formulas - Open Versus Closed Shapes
(OP)
It is my understanding that torsion rotation (angular twist) formulas such as those shown in Section 8.2 of "Design of Welded Structures" by Blodgett are only applicable to closed shapes (such as pipes, round HSS, and rectangular HSS) and open shapes where warping is negligible (such as angles and tee-shapes). For other open shapes, such as wide-flange shapes and channels, one would have to refer to other sources such as AISC Design Guide 9 for proper determination of member rotation in response to torsional loading. Is my understanding correct?
