| Abstract: | The inverse problem of the damage identification for frame structure, which has local damage stiffness, has been studied in this paper. The alternate iterative method in the nonlinear minimizing process has been presented on the base of finite element method and the least square method. The identification results of illustration by this method indicate that: the accuracy is high, and the convergence rate is stable and rapid, the application is convenient. |
