This paper deals with the free vibration characteristics of Mindlin plates that are symmetrically column-supported at four points. The finite difference technique, based on the energy approach, is used. The first lowest four natural frequency parameters are determined for various values of the finite area of the column supports. Detailed results are given for various values of relative thickness ratio and the effects of transverse shear deformation and rotary inertia are examined.
