Thin-walled construction represents a powerful tool for saving steel and thereby for
increasing the competitiveness of steel structures. However, on the other hand, as the limit state of
thin-walled structures is substantially affected by stability phenomena, the above concept can be
implemented just on the condition of post-buckled behaviour being taken into account in the
solution to these stability phenomena. The paper first briefly studies the factors on which the
intensity of the very favourable post-buckling reserve of strength depends and then in detail turns
attention to the most important among them, viz. the effect of the cumulative-damage process that
becomes manifest in the case of bridges and other systems subjected to many times repeated
loading.
