抄録

Based on Mindlin' s plates theory, it is presented a free vibration analysis of plates with stepped thickness. The present analysis of built-in plates, consisting of subpanels different in thickness with a commonupper surface, accounts for the effect of in-plane actions caused by their different mid-surface level. Thus, this analysis takes account of its eccentricity with res pect to a reference plane when treating the conditions of thier continuity. By using the method of superimposition, it is shown that solutions which satisfy identically the differential equation and satisfy the boundary conditions with any desired degree of accuracy are obtained. Eigenvalues of four digit accuracy are provided for a wide range of plate aspect ratios.
