Sensitivity analysis of uncertain structures subject to stochastic load in the framework of SFEM

Abstract

AbstractIn the paper, sensitivity analysis of linear system with uncertain parameters subject to stochastic stationary and non stationary stochastic point process is presented. The proposed approach for the design sensitivity of probabilistic system is formulated in the framework of Stochastic FEM on the basis of the concept of a sensitivity random influence vector in the context of correlation theory i.e. restricted to the probabilistic moments of second order.
