A general one-dimensional model able to study thin-walled beams of open cross-section, exhibiting moderate angles of twist, is presented. It is derived from the 3-D continuous model assuming that the beam cross-section presents a rigid deformation in, and warps out, its own plane. Comparisons with a previous model proposed by Ghobarah and Tso are also made.

Abstract
A general one-dimensional model able to study thin-walled beams of open cross-section, exhibiting moderate angles of twist, is presented. It is derived from the 3-D continuous model assuming that the beam cross-section presents a rigid deformation in, and warps out, its own plane. Comparisons with a previous model proposed by Ghobarah and Tso are also made.File in questo prodotto:
