✦ Synopsis

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 the method, a numerical example is given, and the third-order perturbation method, Kirsch's combined method and the proposed method are compared in the computational accuracy. The results show that the presented method is e!ective.
