This work is an analysis of an accident that occurred in a warehouse during loading of a new multi-level storing frame. The frame was designed in a professional design office with aid of computer program. It is of great importance to carry out checking procedures at various steps of the computerized design process. In this article two different methods were applied in order to calculate the critical buckling force. Then the results were compared. The Euler’s and the Rayleigh’s method yielded convergent results. The both methods proved that the critical buckling force would be exceeded if the frame was fully loaded. Since the frame began to incline when it was loaded only in 80%, other reasons of buckling must also be considered. Although we can’t eliminate designer’s mistake, it is more probable, that the buckling resistance of the frame was reduced by inappropriate operation of hydraulic stackers. The photographs show that the construction was so tightly loaded with palettes, that the overloading was the most probable cause of the catastrophe. The bending moment originated during the loading process could also reduce the buckling resistance of the construction.
