| Abstract: |
Parametric identification of structures is one of the important aspects of structural health monitoring. Most of the techniques available in the literature have been proved to be effective for structures with small degree of freedoms. However, the problem becomes challenging when the structure system is large, such as bridge structures. Therefore, it is highly desirable to develop parametric identification methods that are applicable to complex structures. In this paper, the LSE based techniques will be combined with the substructure approach for identifying the parameters of a cable-stay bridge with large degree of freedoms. Numerical analysis has been carried out and the results demonstrate that the proposed approach is capable of identifying the structural parameters with reasonable accuracy. |
