Abstract EN
Vibration-based method has been widely applied for damage identification of bridge.
Natural frequency, mode shape, and their derivatives are sensitive parameters to damage.
However, these parameters can be affected not only by the health of structure, but also by the changing temperature.
It is essential to eliminate the influence of temperature in practice.
Therefore, a fuzzy neural network-based damage assessment method is proposed in this paper.
Uniform load surface curvature is used as damage indicator.
Elasticity modulus of concrete is assumed to be temperature dependent in the numerical simulation of bridge model.
Through selecting temperature and uniform load surface curvature as input variables of fuzzy neural network, the algorithm can distinguish the damage from temperature effect.
Comparative analysis between fuzzy neural network and BP network illustrates the superiority of the proposed method.
