Abstract
This paper presents a generalization of the classic theory for thin-walled beams by
including distortional displacements. A condensed presentation of the novel finite-elementbased
displacement approach in [1,2] is given, where specific distortional displacement fields,
which decouple the differential equations for generalized beam theory (GBT), are determined
via a semi-discretization procedure. The distortional displacement fields are found as solutions
to a distortional homogeneous eigenvalue problem which produce distortional displacement
eigenmodes. Using the distortional modal matrix found for the homogeneous system the
final uncoupled set of distortional differential equations including the load terms are presented
and the full solution is given, including an illustrative example. This new approach is
an alternative to the traditional first order GBT method.
