给出了求弹性支承连续柱的最低弹性临界荷载的精确方法，以及求梁和柱的网格中的柱从梁得到的面外支承的刚度的精确方法。网格的梁和柱不需要是相同的、均匀的或均匀间隔的。然而，一根梁的抗弯刚度分布必须遵循任何其他梁的比例，柱的抗弯刚度（和轴向力）必须类似地相互关联。准确的方法需要计算机。为此，给出了设计曲线和近似计算方法.因此，可以使用手工计算来获得平面外网格屈曲载荷或设计具有所需屈曲载荷的网格。无论弹性支承的来源如何，柱法都适用;当支承的柱被适当的相互关联的结构所代替时，梁法适用。（作者/TRRL）
Exact methods are given for finding the lowest elastic critical load of a continuous column with elastic supports, and for finding stiffness to represent the out of plane support which the columns of a grid of beams and columns receive from the beams. The beams and columns of the grid need not be identical, uniform or evenly spaced. However, the flexural rigidity distribution for one beam must follow from that of any other beam by scaling, and the column flexural rigidities (and axial forces) must be similarly interrelated. The exact methods require a computer. Therefore design curves and approximate methods are also given. Hence hand calculations can be used to obtain out of plane grid buckling loads or to design grids with required buckling loads. The column methods apply regardless of the source of the elastic supports, and the beam methods apply when the supported columns are replaced by suitably interrelated structures. (Author/TRRL)
