✦ Synopsis

A study of the coupled flexural-torsional vibrations of monosymmetric beams is presented. The effects of warping stiffness, shear deformation and rotatory inertia are taken into account in the formulations. Numerical results are given for three cantilever beams both including and excluding the effects of warping stiffness. It is seen that as the modal index and the thickness of the beam increase, shear deformation, rotatory inertia and warping effects become more pronounced on the natural frequencies, and therefore the errors can be unacceptably large if these effects are ignored.

An exact analytical method is presented for the analysis of forced vibrations of uniform, open-section channels. The centroid and the shear center of the channel cross-sections considered do not coincide; hence the flexural and the torsional vibrations are coupled. In the context of this study, the

The objective of the present paper is to analyze coupled bending and torsional vibrations of distributed-parameter beams. The governing coupled set of partial differential equations is solved by separating the dynamic response in a quasistatic and in a complementary dynamic response. The quasistatic
