Buckling strength predictions are presented for a wide range of thin isotropic skew plates. The key studied parameters include the aspect ratio, skew angle, and rotational restraint stiffness on the different edges of the plate. The buckling strengths are evaluated both for isolated plates and for plates that are continuous with other parts of the structure. The assumed loading is uniform, uniaxial compression. The buckling predictions are presented in the form of dimensionless buckling curves, which permit a ready adoption into the “data sheets” commonly used in current design. The buckling predictions demonstrate the effect of introducing symmetrical combinations of elastic restraints against rotation on the edges of isolated skew plates. Further, they are presented in a manner that allows the benefits of continuity over skew bays to be evaluated. The curves also illustrate the complex character of the buckling mode changes that take place with a change in aspect ratio in skew plate structures. In addition, these mode changes lead to well defined local optima, which the designer can exploit if he has control over the aspect ratio of a skew plate.
