Abstract
Abstract: Based on the theory of model analysis, the general variation of model parameters, such as the structure natural frequency, displacement mode, curvature mode and strain mode etc.model of reinforced concrete beams with different damage locations and different damage states are reversely studied by finite element numerical simulation with the pre-damaged reinforced concrete beam structure as the research object, model and the aptability, sensitivity in the reinforced concrete structure damage identification are discussed. The results show that the frequency and displacement mode can not effectively reflect the existence of structural damage, but curvature mode and strain mode can reflect the structural damage condition. The structural damage identification based on curvature mode and strain mode method can be used for damage identification of large complex reinforced concrete bridge structure.
