What is A modified Vlasov theory for dynamic analysis of thin-walled and variable open section beams about?

The equations of motion of thin-walled beams with open cross-section considering the effects of shear flexibility, rotatory inertia in the stress resultants and variable cross-sectional properties are presented. These equations are based on Vlasov's theory of thinwalled beams, which is modified to include the effects indicated above. The formulation is also applicable to solid beams, constituting therefore a general theory of coupled flexure and torsion of straight beams. The differential equations are shown to be particularly suitable for analysis in the frequency domain using a state variables approach. The resulting equations are used in the determination of the natural frequencies and the seismic response of a building provided with a thin-walled reinforced concrete core to resist lateral loads. Finally, an example of a variable section channel beam is presented, which provides additional evidence on the generality of the formulation.
