Advanced Optimal Modal Reduction and Optimal Sensors Location Procedures for Structural Damage Identification

S. OUAKNIN, Y. GOLDFELD

Abstract


A two steps sub-structuring strategy is proposed for possible implementation in identification procedure. In the first step- the most important modes for a chosen master are defined with the aid of the OMR technique. In the second step – the optimal set of DoFs in the slave sub-structure is evaluated, with respect to the modal responses of the main sub-structure for the obtainable set of modes. Identification procedure, based on GA, demonstrate the efficiency of the proposed procedure by numerical example.
