	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. Detailed record
	The influence of non-proportional damping on forced vibration of continuous multispan girder Hračov, Stanislav ; Náprstek, Jiří ; Pospíšil, Stanislav The article deals with an influence of the proportional and non-proportional damping on forced vibration of continuous multispan girder. the solution is formulated in generalized coordinates, which are the eigen-functions of undamped system. The solutions of classical method and analysis including non-proportional damping are comparing. Detailed record
	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. Detailed record
	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. Detailed record
	Modelový výzkum větru pro památkovou péči Pospíšil, Stanislav ; Drdácký, Miloš ; Slížková, Zuzana ; Lesák, Jaroslav ; Knotková, D. The paper presents by means of case studies some possibilities of wind tunnel model research into the action of wind on monuments. The first case describes investigations of the behaviour of gothic sandstone pinnacles during cyclic action of various combinations of climatic loads. Further, the problems of wind pressure and eddies and flow around historic buildings are presented. The last example studies surface degradation of complex architectural forms due to atmospheric pollution. Detailed record
	Along wind random vibrations of a slender structure - modelling by concentrated masses Náprstek, Jiří ; Pospíšil, Stanislav The paper presents an analytical-numerical solution to the along wind random response of slender structures to fluctuating stationary wind velocity component.The structure has been modelled using a linear system discretized by concentrated masses or by FEM, respectively. Detailed record
	Along wind random vibrations of a slender structure - modelling by continuous elements Náprstek, Jiří ; Pospíšil, Stanislav Along wind random vibration of a slender structure represents one of the most important aeroelastic effects resulting from wind - structure interaction. The theoretical model being based on one-dimensional elements with continuously distributed mass and stiffness has been introduced in this paper. Detailed record
	Numerical analysis of interaction of a moving body and streaming medium with high Re number Král, Radomil ; Pospíšil, Stanislav ; Náprstek, Jiří The paper presents an ability of finite element method in the fluid dynamics, particularly in a civil engineering. Detailed record
	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. Detailed record
	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. Detailed record
