A two-step approach based on coupled static and dynamic structural responses is proposed for local damage identification in this study.

Abstract

A two-step approach based on coupled static and dynamic structural responses is proposed for local damage identification in this study. Firstly the suspicious damaged elements are predicted by calculating the residual force vector which is derived from the equation of static equilibrium. As the suspicious damaged elements are determined, a response sensitivity based model updating method is applied to quantify the damage extents. The proposed method is verified with both single and multiple damages identification from several numerical simulations. Local damages can be identified successfully from the proposed method and the damage extents are in good agreement with the true values. The results of the simulation also show that the proposed method is insensitive to the artificial measurement noise.
