A DISCUSSION ON THE ANALYTICAL SOLUTION OF RECTANGULAR THIN SLAB UNDER TEMPERATURE LOAD WITH FOUR SIMPLY SUPPORTED EDGES

Based on the small deflection plate theory, the equilibriumdifferential equation of isotropic thin slab with a temperature variation perpendicular to surface is deduced, by assuming a deflectionfunction which satisfies the equilibrium differential equation andusing the Levy method. An analytical solution is obtained for the case with four simply supported edges, which provides a basis for subsequent engineering calculations.
