Abstrait:

Based on the modal analysis theory of bridge dynamic characteristics, a pre-damaged reinforced concrete model beam is established by ANSYS as the object of analysis. The regularity of modal parameters such as displac, ement mode and curvature mode of the model beam at the preset damage location and different damage degree and the identification of modal parameters in structure damage are studied by finite element numerical analysis. Sensitivity. The results show that the displacement mode is difficult to identify the damage of the structure effectively, but the curvature mode can reflect the damage of the structure more accurately. The damage identification method based on the curvature mode can be applied to the damage diagnosis of the structure in practical engineering.
