GBT-D cross-section analysis for generic thin-walled members

This paper presents an enchanted dynamic approach for the cross-section analysis of generic multi-components thin-walled members within the framework of the Generalized Beam Theory (GBT). The approach includes the partial interaction behavior taking place at the interface between components forming the cross-section, thus extending the GBT-D methodology recently developed by the authors. The proposed approach is able to provide the full set of trial function with a very simple, not recursive procedure based on the solution of a very limited number of eigenvalue problems. Obtained deformation fields are naturally global in type and hierarchically ordered, in addition to be very precise from the point of view of accuracy and symmetry. The easy of use and the high quality of the proposed approach are pointed out through an illustrative example.
