Cross sectional properties of thin-walled composite beams

Research output: Conference contribution

Abstract

In the design of composite sections beam theories are used, which require the knowledge of the cross sectional properties, i.e. the bending-, the shear-, the torsional-, the axial stiffnesses and the coupling terms. In the classical analysis the properties are calculated by assuming kinematical relationships, e.g. cross sections remain plane after the deformation of the beam. These assumptions may lead to inaccuracy or to contradictory results. In the paper a new theory is presented, in which no kinematical assumption is applied, rather the properties are derived from the accurate (three dimensional) equations of beams using limit transition. The theory includes the shear displacements both in the inplane and in the torsional deformations, and it is applied both for open and for closed cross sections.
