Coupled Flexural-Torsional Vibrations of Thin-Walled Beams with Monosymmetric Cross-Section
This paper presents the coupled flexural-torsional vibration of uniform thin-walled beams having single cross-sectional symmetry. The beam model is based on the Timoshenko beam theory including warping effect. The governing differential equations for free vibration of such beams are solved numerically to obtain natural frequencies and mode shapes. Numerical results are calculated for three specific examples of beams with free-free, clamped-free, hinged-hinged, clamped-hinged and clamped-clamped end constraints. The effect of warping stiffness on the natural frequencies and mode shapes is discussed and it is concluded that substantial error can be incurred if the effect is ignored.
