Analiza stanu zakrytycznego tarczy prostokątnej poddanej działaniu mimośrodowego ściskania i jej zastosowanie do przybliżonego obliczania cienkościennego dźwigara skrzynkowego

The post-buckling state analysis is considered of a rectangular plate, simply supported along their edges, subjected to the bending and compression. The deflection has been determined as well as bending and membrane stresses and in-plane displacements of a plate by means of compressive force and in-plane bending moment values. The approximate method which allows to determine the stresses distribution in thin walled girders is described. The method is based upon the fact, that the webs work as simply supported rectangular plates subjected to the bending and compression.
