Skew Supported Members with Saint-Venant Torsion

The two usual assumptions are made. The members are slender, e. g. the spans exceed by far the largest extension of the cross sections, and Saint-Venant torsion alone provides a suitable basis for analysis. The torsionai property of a member is thus described completely by its torsionai rigidity G K which is again given in Fig. 4.1 for a rectangular and a monocellular, hollow cross section [v. Eqs. (1.9) and (2.5)].
