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.

Parametric sensitivity analysis of the stress state in the crack-prone areas of breathing webs
Kala, J. ; Kala, Z. ; Škaloud, Miroslav ; Teplý, B.
Within the framework of the Czech research on the cumulative damage process in, and the fatigue limit state of, steel plate girders under the action of many times repeated loading, the authors decided to perform a sensitivity analysis of the effect of initial imperfections on the state of stress in those areas of the breathing webs of the girders in which fastigue cracks develop under the effect of repeated loads. This paper describes a preparatory stage of the study; in whitch the theoretical apparatus needed is prepared, discussed and calibrated by way of comparing theoretical results obtained with the results of the tests carried out by one of the authors and his co-workers some time ago.
