An analytical method is presented to determine the stresses in flat plates near columns. It is based on the flexural theory of elastic plates. The method takes into account the shape of the column and the dimensions and boundary conditions of the plate. The analytical values thus obtained are com-pared with the corresponding values obtained by other methods. Perfect agreement exists with more elaborate methods based on plate theory. Concerning approximate methods, theoretical inconsistences are pointed out to explain the differences in results. The analytical values, furthermore, are compared with test results and good agreement can be realized. Simplified formulas are suggested for design purposes.
