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.
Timber frame resistant against earthquake
Pospíšil, Stanislav ; Kasal, Bohumil ; Drdácký, Miloš
Experimental research and development of earthquake resistant timber frame joints are described in the paper. Reduced and full scale models were tested on shaking tables. The joints are strengthened with FRP sheets.
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.
Study of combined climatic influences and hydrophobization effects on sandstone pinnacles from the Santa Barbara church in Kutná Hora
Drdácký, Miloš ; Lesák, Jaroslav ; Slížková, Zuzana ; Pospíšil, Stanislav ; Delpech, P.
The report summarizes results of the first part experiments in the Jules Verne climatic wind tunnel CSTB in Nantes. It presents diagrams of temperature and moisture changes measured on both the exterior surface and inside historic sandstone pinnacles from the church of Santa Barbara in Kutná Hora at different combinations of climatic loads with changing temperature, rain and wind velocity characteristics. Thermography has been applied for surface temperature measurements. During the tests the hydrophobization effect was studied, too.
Empirical mode analysis of the non-stationary response of the structure vibrating in the wind
Pospíšil, Stanislav ; Náprstek, Jiří
The paper describes the new method of analysis of the response of structure in the wind.
Non destructive observation of damage processes by X-Ray dynamic defectoscopy
Vavřík, Daniel ; Jakůbek, J. ; Pospíšil, S. ; Visschers, J. ; Zemánková, Jaroslava
The subject of this work is experimental observation of the development of internal damage and its evolution in aluminium alloy flat specimens with different configurations of the pre crack. We propose direct and non-destructive observation of the material damage evolution by measuring changes in transmission of X-rays penetrating a stressed material, using a single photon counting X-ray imager, called Medipix 1.
Instability onset of rectangular prismatic beams in the wind flow
Pospíšil, Stanislav ; Fischer, Cyril ; Náprstek, Jiří
This paper describes a part of theoretical and experimental researchdealing with the problem of the aeroelastic instability onset ofslender rectangular beams in the air stream, modeled as twodegrees-of-freedom.
Resolution and stability tests of Medipix-1 pixel detector for X-ray dynamic defectoscopy
Jakubek, J. ; Vavřík, Daniel ; Pospíšil, S. ; Visschers, J.
The application of the Medipix-1 pixel detector device for directnondestructive observation of damage development in graduallystressed materials by means of X-ray transmission measurements(so called X-Ray Dynamic Defectoscopy -XRDD) has been recentlysuccessfully demonstrated.
Aeroelastic instability of a system with nonconservativeand gyroscopic forces
Náprstek, Jiří ; Pospíšil, Stanislav
Mathematical model of stability loss due to flutter effect.The origin of instability consists of nonconservative andgyroscopic forces.
