Combination of modal responses consistent with seismic input representation
TL;DR: In this paper, a simplified procedure for evaluation of correlation coefficients and peak factors consistent with the power spectral density of seismic excitation is proposed, based on an approximate analytic expression for direct evaluation of the energy spectral density consistent with any prefixed response spectrum.

Simulation of Stochastic Fields by Statistical Preconditioning
TL;DR: In this article, a new stochastic fields simulation technique that can realize prescribed means and covariances with a substantially smaller sample size than that of other existing methods is developed, utilizing the modal decomposition of the covariance matrix of the correlated random vector and the spectral representation of random processes.

Simulation of pavement roughness and IRI based on power spectral density
TL;DR: The international roughness index (IRI) for evaluating pavement surface roughness is simulated using the power spectral density (PSD) of pavement surface fluctuation and can be simply calculated by means of the square root of the sum of the weighted regression coefficients of PSD roughness.
