Spectrum Analysis of The Gate of Dike Structure Under Nonstationary Random Loading
Keywords:
Random loading, seismic excitation, no stationary processAbstract
This paper investigates the nonstationary random excitations with a constraint on meansquare value such that the response variance of a given linear system is minimized. It is also
possible to incorporate the dominant input frequency into the analysis. The excitation is taken to
be the product of a deterministic enveloping function and a zero mean Gaussian nonstationary
random process. The power spectral density function of this process is determined such that the
response variance is minimized. The numerical results are presented for multi-degree freedom
system and modeled to predict the behavior of the gate of dike Structure under random water
