✦ Synopsis

This paper presents numerical study about the in#uence of the shear #exibility, due to either bending and warping, on the out-of-plane free vibration of continuous horizontally curved thin-walled beams with both open and closed sections. This study was made by means of a recently developed "nite element formulation for shear deformable curved thin-walled beams. The model is brie#y reviewed and is used to obtain natural frequencies of continuous I-beams and box beams. A parametric study was performed in order to elucidate the in#uence of shear deformability, on the dynamic behavior of continuous thin-walled curved beams, for di!erent slenderness ratios, cross-sectional characteristics and boundary conditions.

In this paper, a theoretical model is developed for the dynamic analysis of composite thin-walled beams with open or closed cross-sections. The present model incorporates, in a full form, the shear flexibility (bending and warping shear) as well as a state of initial stresses. This allows to study t

The governing di!erential equations for out-of-plane vibrations of curved non-uniform beams of constant radius are derived. Two physical parameters are introduced to simplify the analysis. The explicit relations between the #exural displacement, its "rst three order derivatives and the torsional dis
