Pokritiké působení, jeho částečná eroze a mezní stav únavy ocelových nosníků namáhaných opakovaným zatížením
Škaloud, Miroslav ; Zörnerová, Marie
Thin-walled construction as a powerful way to saving steel and the stability limitations involved are discussed. It is shown that this promising trend can be materialised just thanks to the beneficial effect of so-called post-buckled behaviour. As a great part of steel structures are subjected to repeated loading (bridges, crane-supporting girders and the like), it is demonstrated by the results of numerous experiments how the post-buckled reserve of strength is affected by the cumulative damage process generated by the many times repeated character of the loading, and its impact on design is shown.
