Abstract

A procedure based on the stochastic central difference method that was presented earlier by the author has been extended to cases involving with spatially and temporally stochastic structural systems that are approximated by the versatile finite element method. It is believed that for the first time nonstationary random responses of this class of systems are considered. The procedure eliminates the limitations associated with those employing the so-called stochastic or probabilistic finite element methods. Owing to its simplicity, the proposed method can easily be incorporated into many commercially available finite element packages.
