✦ Synopsis

A new numerical approach for solving the vibration of a beam resting on an elastic foundation is proposed. The approach uses the dierential quadrature (DQ) to discretize the dierential eigenvalue equation de®ned on each element, the transition conditions de®ned on the inter-element boundary of two adjacent elements and the boundary conditions of the beam. It is the dierential quadrature element method (DQEM) analysis model of the vibration of beams resting on elastic foundations. Numerical results obtained are presented. They prove that the developed DQEM analysis model is ecient and reliable.
