Abstract:

Structural damage is too difficult to identification. In this paper, a new method using grey forecasting model to identification the structural damage with past and present data is proposed. Firstly, proposed a novel grey forecasting model. Secondly, three grey forecasting models are compared. Finally, proposed a novel method to identification structural damage. Large structure systems include natural decay and unnatural decay. Natural decay modal parameter can be get from the grey forecasting model, compare with the modal parameter identify currently, by a set value to analysis structural damage. Experimental results verify the theoretical analysis.
