This work will investigate the behaviors of Moving distributed masses of orthotropic rectangular plates resting on bi-parametric elastic foundation with clamped-clamped end conditions. The governing equation is a fourth order partial differential equation with variable and singular co-efficients. The solutions to the problem will be obtained by transforming the partial differential equation for the problem to a set of coupled second order ordinary differential equations using the technique of Shadnam et al[18] which shall then be simplified using modified asymptotic method of Struble. The closed form solution will be analyzed, resonance condition shall be obtained and the result will be presented in plotted curves for both cases of moving distributed mass and moving distributed force.

Bi-parametric foundation,orthotropic, foundation modulus, critical speed, resonance, modified frequency.
