摘要：
The paper presents a hybrid finite-element model for calculation of stresses and deformations of thin-walled beams of any cross section (open, closed or mixed). The present model takes into account shear deformations and allows one to deal with beams with sharp variations of the cross section. The numerical performance of the proposed element in dealing with warping torsion is assessed by a number of meaningful examples.
