โœฆ Synopsis

This work presents a method to find the exact vibration frequencies of beams resting on variable one- and two-parameter elastic foundations. The proposed solution is based on a new method that enables one to find the dynamic stiffness matrix for the member including the effects of the variable foundation stiffness. The natural frequencies of vibrations are found as the frequency that causes the determinant of the stiffness matrix to be equal to zero. Several examples are given and compared to published results to demonstrate the accuracy and flexibility of the method.

A new finite element model of a Timoshenko beam is developed to analyze the small amplitude, free vibrations of non-uniform beams on variable two-parameter foundations. An important characteristic of the model is that the cross-sectional area, the second moment of area, the Winkler foundation modulu
