| Abstract: | The procedure of using structural dynamic response to idenfity parameters and inverting the input history simultaneously is called composite inversion. Ground motion composite inversion based on a substructural analysis method is studied in this paper. Combining the decomposition of the structural stiffness matrix with an identification approach with unknown input, a method of composite inversion is suggested. The validity of the method offered is proved by numerical simulation examples. |
