Existing theory and the associated computer program VICONOPT deal with infinitely wide plate assemblies given that boundary conditions on all sides of each panel form a rectangle. They also deal with cases when the four supports form a parallelogram so that the plate is a skew plate. This is true provided the panel is of finite width. i.e. isolated from any adjacent panels, which is the case commonly modeled in practice. It does not represent what happens in the real structure however, where normally there is continuity with the adjacent panel. The present paper shows how the theory and the computer program VICONOPT, can be modified such that skewed plate assemblies that are infinitely wide and repeat at transverse intervals can now be modeled exactly. The paper also shows that the theory can be used, if a small measure of approximation is accepted, to model this situation by analysing only one of the identical stiffeners with associated panel skin in the common situations where the panel has equally spaced, identical, longitudinal stiffeners between each adjacent pair of longitudinal lines of support. Illustrative results are given.
