Deterministic seismic analysis of cabinet facility does not reflect the real behavior of the system with the uncertainties of material parameters. This paper investigates the effects of uncertain properties in the context of random field theory for the stochastic dynamic response of cabinet. The influences of different decomposition methods (i.e. Cholesky, Eigen, and modified Cholesky) with various correlation lengths of the spatial material distribution are explored. The responses are compared to the case where no variation is applied in the properties of the model.
