Full Article:

This papers investigates the application of first order Taylor expansion considering reciprocal intervening variables for estimating second order statistics of the response of uncertain linear static structural systems. Results presented in this contribution indicate that for estimating second order statistics, the applied expansion is more accurate than approaches based on first and second order Taylor series proposed in the literature while numerical efforts associated with the implementation are similar
