With the dynamic element method (DEM), results more accurate than with the conventional finite element method (FEM) are obtained with the same number of degrees of freedom. This is due to the introduction of shape functions of polynomial type, introducing frequency dependence into the mass matrix ex

Since, especially for higher frequencies, Timoshenko's theory gives more reliable results than EulerβBernoulli's theory, systems of beams, like frames, under arbitrary dynamic excitations should be analyzed on the basis of this refined theory. In this paper, after deriving the basic fundamental solu
