Abstract: The small deflection theory of skewed stiffened plates under uniform load is treated by means of a Fourier series. The general solution considers simple support conditions along two opposite edges and the conditions of elastic support, with or without torsial restraint along the other two edges. By introducing certain parameters in some terms of the boundary equations, only one solution computer is required to obtain moments and shears anywhere on the plate. Results from several trial cases with different harmonics in the Fourier series solution indicated that ten harmonics give good convergence. For the common range of practical values of skew angle and skew aspect ratio of the plate, the results obtained converged satisfactorily from the engineering viewpoint.
