Abstract: Warping stresses have been evaluated in circular and strip concrete slabs resting on the ground by idealizing the foundation medium by the Reissner foundation. Linear temperature variation which increases with depth of slab and which results in partial support of the slabs has been considered. The results for deflection and moment coefficients have been presented for various values of nondimensional length A, load coefficients Q, and ratios of relative stiffness to shear stiffness. The results indicate that the shape of the slab has influence on maximum stresses and deflections up to A = 6. Further, the stresses in slabs on the Reissner foundation are higher than the stresses in the same slabs when they are placed on the Winkler foundation.
