✦ Synopsis

Numerical experiments performed on vibrating orthogonal beam grillages rigidly clamped at two adjacent edges are reported. The first five natural frequencies of transverse vibrations have been determined by using a finite element code developed at the Solid Mechanics Division of Universidad Nacional del Sur, for which Timoshenko's mathematical model has been implemented. By introducing discontinuities in the beam components it is possible to attain structural weight reduction and an increase in the fundamental frequency. Accordingly, dynamic stiffening is achieved.

By introducing continuous or discontinuous variations in the thickness of beams, arches and plates, it is possible in many practical situations to raise the value of the fundamental frequency and, at the same time, to lower the weight of the structural element. This is a beneficial situation, especi

The dynamic sti!ness matrix of a centrifugally sti!ened Timoshenko beam has been developed and used to carry out a free vibration analysis. The governing di!erential equations of motion of the beam in free vibration are derived using Hamilton's principle and include the e!ect of an arbitrary hub rad
