In a paper by Parsons and Cook, a theoretical solution to the initial buckling under shear stress of a long clamped plate with parallel edges, reinforced by a stiffener mesh was obtained. In the particular case when only diagonal stiffeners are present (having flexural rigidity only) one numerical solution was obtained for a particular value 1·5 of the aspect ratio of the panels of the plate associated with various values of θ, for which a partial check on the accuracy of the computational work could be carried out by comparison with results obtained by Southwell and Skan.
In this paper the numerical work is extended to cover a range of values of θ and a range of values of the aspect ratio in order to determine the optimum arrangement of stiffeners in resisting shear stress applied to the plate, that is to say the arrangement which maximises the onset of buckling.
As in Ref. 1, the cross-sectional area of the stiffeners is neglected, (he effect of a finite area of cross section being discussed in a subsequent paper.
