Abstract:In this paper, structural system identification with incomplete input information is studied. On the basis of study of the existed methods for multiple inversion, prediction-correction iterative approaches for input and system identification are further studied. Because this class of methods were not proved theoretically, they have been doubted all the time, this paper put emphases on one iterative approach for multiple inversion, and the other method for multiple inversion with unknown ground motion is studied in another paper. From theory analysis and numerical examples, it can be seen: this method has the same applicable condition as Compensation Method when the iterative produce is convergent. And a new two-step method for multi-inversion is proposed.
