✦ Synopsis

Thin-walled beams with open cross-section under torsion or complex load are studied based on the hypotheses of the classical theory (Vlasov). Di erent from previous techniques presented in the literature, the concept of a strip-plate is introduced. This concept is used to accurately model the e ect of bending induced by torsion and to deÿne an alternate ÿnite element called macro-element. The macro-elements are shown to model more accurately the thin-walled beams under warping torsion or complex load therefore giving better results than the classical theory.
