Nonstationary Random Critical Seismic Excitations
Publication: Journal of Engineering Mechanics
Volume 113, Issue 4
Abstract
A method is presented to find nonstationary random seismic excitations with a constraint on mean square value such that the response variance of a given linear system is maximized. 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 stationary random process. The power spectral density function of this process is determined such that the response variance is maximized. Numerical results are presented for a single‐degree system and an earth embankment modeled as shear beam.
