✦ Synopsis

Based on the usual perturbation and PadeH approximation, a new eigenvalue reanalysis method for modi"ed structures is developed in this paper. By this method, the accuracy of the eigenvalues and varying ranges of the parameters of the structures are improved. As an application of the method, a numerical example is given and the second-order perturbation method and the proposed method are compared in the accuracy of eigenvalues and range of parameters. The results show that the present method is e!ective.

Based on the usual perturbation and PadeH approximation, a new static displacement reanalysis method for structures is developed in this paper. By this method, the accuracy of the static displacements for moderateto-large modi"cations of the parameters of structures is improved. As an application of
