STability of linear stochastic systems

Resumo

In this paper the problem of modeling the movement of the linear system under the influence of determined and stochastic parametric load had been studied by the example of cable-stayed girder. The aerodynamic stability of similar systems had been analyzed. There are two cases compared when pulsation wind component is Gauss random stationary process with a spectral density of Davenport, and spectral density of Kaimal.
