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.

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.

Analysis of a bar-system with elements of variable cross-section characteristics
 Náprstek, Jiří ; Fischer, Cyril
The response analysis of a system consisting of bars or one-dimensional elements can be understood as a solution of a certain differential system on an oriented graph. This graph is a corresponding geometric representation of a mechanical system investigated where elements of this graph are individual bars of the system.

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.

Analysis of a bar-system with continuous parameters solving differential equation on an oriented graph
 Náprstek, Jiří
Theoretical analysis of many structures in civil or mechanical engineering can be done using a mathematical model based on a system of bars with continuously distributed parameters.

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.

Vaveletový rozklad nestacionárního náhodného signálu
 Fischer, Cyril ; Náprstek, Jiří
The paper provides a support for the wavelet based approach for the analysis of the MDOF systems subjected to non-stationary excitation. It tries to cover the lack of input data in the form of the wavelet decomposition of seismic records.
