EFFECTS OF FRICTION FORCE ON THE VIBRATION OF A BEAM ON AN ELASTIC FOUNDATION
Dynamic responses of an axially loaded beam on an elastic foundation can be reduced by considering the friction forces on both ends of the beam. Closed-form shape functions for an axially loaded beam on an elastic foundation are obtained by solving the governing differential equation. Shape functions change as the inertia force in the beam segment is smaller than, equal to or greater than the foundation force. Numerical results demonstrate that there is always an optimum axial force at a joint in order to have the maximum dissipation of energy for the structure. The effect of foundation modulus does not significantly influence the value of the maximum response of the beam, but influences the frequency of the occurrence under the dynamic excitation.
