Abstract EN
The paper presents an effective approach for damage identification of bridge based on Chebyshev polynomial fitting and fuzzy logic systems without considering baseline model data.
The modal curvature of damaged bridge can be obtained through central difference approximation based on displacement modal shape.
Depending on the modal curvature of damaged structure, Chebyshev polynomial fitting is applied to acquire the curvature of undamaged one without considering baseline parameters.
Therefore, modal curvature difference can be derived and used for damage localizing.
Subsequently, the normalized modal curvature difference is treated as input variable of fuzzy logic systems for damage condition assessment.
Numerical simulation on a simply supported bridge was carried out to demonstrate the feasibility of the proposed method.
