Jednoduchá metoda navrhování stěn ocelových mostních nosníků s nízkými výrobními náklady - jeden z nových výsledků pražského výzkumu dýchání stěn
 Škaloud, Miroslav ; Zörnerová, Marie
The main impact of the latest stage of the Prague research on web breathing is the derivation of simple user-friendly formulae such as to make it possible completely to disregard the parasitic effect of the cumulative damage process generated by web breathing. Thereby the way is paved to the application of simple economic-fabrication structural systems in bridge construction, consisting for example of singly-symmetric steel beams made composite with a concrete slab. Such systems substantially reduce the amount of labour needed, and hence the fabrication costs, and that is why they may in numerous cases prove to be advantageous and preferable for small and medium-span bridge structures.

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.

Experiment - spolehlivý zdroj informací pro odvození metod návrhu tenkostěnných ocelových nosníků namáhaných na únavu
 Škaloud, Miroslav ; Zörnerová, Marie
The limit state of thin-walled steel girders subjected to many times repeated loading is to a great extent affected by the cumulative damage process occuring in the girder webs \"breathing\" under repeated loads.Based on experimental results various approaches to the definition of the fatigue limit state of the above girders are discussed, a number of potential design procedures suggested by other researches validated and set of S-N curves, established so as to serve as a reliable tool for the fatigue analysis of thin-walled girders with \"breathing\" webs presented
