In [1] a method is presented which makes possible the prediction of nonlinear behaviour of structures in the initial loading range for imperfect buckling situations. In the present note a new derivation of the fundamental formula is given. This derivation is considerably shorter and thus easier to understand. Special emphasis is laid on the assumptions that must be made to obtain this formula. 相似文献
