	Influence of random material heterogeneity on longitudinal harmonic wave propagation Náprstek, Jiří The paper deals with mathematical modelling and properties of linear longitudinal wave propagating in one dimensional body with random imperfections in material density and Young modulus. Detailed record
	Post kritické limitní stavy a nestacionární odezva aeroelastického systému Náprstek, Jiří ; Pospíšil, Stanislav ; Fischer, Cyril The paper deals with the clasification of stability and limit cycles of two dimensional aeroelastic system. Detailed record
	Numerické a experimentální řešení nelineární aeroelastické odezvy nosníku mostu Pospíšil, Stanislav ; Král, Radomil ; Náprstek, Jiří ; Hoffer, R. ; Lachmann, S. Analysis of the bridge girder under self-excited load is performed numericaly and experimentally. Detailed record
	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
	Numerická analýza v Fokker-Planckovy rovnice pro soustavy s multiplikativními a aditivními šumy Náprstek, Jiří ; Král, Radomil In the present study simple conditions are selected to demonstrate that the idea of FEM application for this purpose is realistic. FEM abalities are demonstrated discussing a couple of single degree of freedom systems. Detailed record
	Základní rysy numerického řešení Fokker-Planckovy rovnice pomocí metody konečných prvků Náprstek, Jiří ; Král, Radomil The Fokker-Planck equation represents a powerful tool for an investigation of probabilistic properties of dynamic systems subjected to random excitation.The paper deals with a possibility to solve this equation using Finite Element Method - FEM. Specific properties of the Fokker Planck operator have been respected and special problem oriented elements have been developed. 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
	Aeroelastický model s Froudeovým číslem a bez něho Pirner, Miroš ; Fischer, Ondřej ; Urushadze, Shota The article presents some problems related to experimental verification of footbridge vibrations excited by wind and pedestrian loads on models with and without the Froude number. 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
