Redukovaný problém nelineární aeroelastické stability a příslušné post-kritické stavy
Pospíšil, Stanislav ; Náprstek, Jiří
This paper deals with the development of a uniform theory based simultaneously on theory and experiments which would cover known cases of aeroelastic instability and restabilisation due to non-linear and non-symmetrical terms.
Náhodná odezva jednorozměrné konstrukce s neproporcionálním tlumením vlivem působení větru
Náprstek, Jiří ; Pospíšil, Stanislav ; Hračov, Stanislav
In this study linking with the last year´s paper theoretical results and basic properties of the system are briefly remembered.Then the authors are focused on an analysis of the particular structure.
Posouzení hangaru pro civilní letadla na účinky větru s ohledem na odolnost a stabilitu konstrukce
Král, Radomil ; Pospíšil, Stanislav ; Náprstek, Jiří
The paper assess a behaviour and an impact of the air flow on two hangar buildings. Special attention was devoted to the roofing constructions.
Compliance criteria to be proved by the analysis of a civil engineering structure
Fischer, Ondřej
Any (not only) civil engineering structure must meet two fundamental requirements: the safety and serviceability before being put into service. While the safety is in general controlled by the loading and behaviour of the structure and by the resistance of its materials, which all are strongly supported by Codes and software packages, the serviceability is often left on the account and experience of the engineer. Some reflections and examples of failures are given in what follows.
Life-time prediction of slender structures subjected to turbulent wind
Pospíšil, Stanislav ; Lahodný, J. ; Janata, J. ; Urushadze, Shota
The paper describes the prediction of theoretical life-time of antennas made from glas-reinforced laminate and the comparison with long time measurements on the real structures.
Modelování nelineárních aeroelastických jevů na konstrukcích
Náprstek, Jiří ; Pospíšil, Stanislav ; Hračov, Stanislav
The paper deals with the aeroelastic instability and non-linear post-critical behaviour of a two degree-of-freedom system.
