A theory for analysing moments, shear, and defletions in plates is outlined, and a method for developed for its application to flat slab and flat plate structures. The slab is considered as floating on the surface of a liquid; each load and each reaction is applied seperately to the floating slab, and these separate effects are summed to give actual moments, shears, and deflections in the structure. Theroy is applicable to panels of any shape - square, rectangular, triangular, or trapezoidal - with any type of loading. The method allows for any degree of restraint or fixity between slab and column. Application of the theory in this paper is limited to internal panels with known column reactions, and tables are presented for the quick determination of moment, shear and deflection at any point of the panel.
