摘要：The sensitivity and significance levels of design parameters to modal eigen-values have been performed to investigate the reasonability of parameters selection for model updating based on finite element (FE) model simulation of a cable-stayed bridge laboratorial model. The analysis indicates that sensitivity analysis has clear conception and easily to be applied to practical engineering, but the results show partly and qualita- tively the sensitivity of design parameters. Variance analysis, based on testing samples generated by full factorial design, orthogonal design, Taguchi design, uniform design and central composite design of design of experiment (DOE) in the global design space, were discussed and contrasted for significance analysis, the results could quantitatively show the significance levels of design parameters to modal eigenvalues, and the optimal method of DOE discussed above is central composite design. ? 2010 ICIC International.
