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.
Probabilistic reliability assesment of steel planar frames
Křivý, V. ; Marek, Pavel
In connection with the transition to a probabilistic reliability assessment of systems, it is necessary to evaluate the suitability of particular transformation models serving as tools for transforming the loading into the response of the structure to the load with regard to the substance of the stochastic method. In this connection attention is paid to the transition from the traditional assessment of buckling strength standards to the “strength stability concept” with respect to the effects corresponding to the second order theory.
