Damage identification of a concrete cantilever beam based on Elman neural network

摘要

Elman neural network is presented to identify and locate the crack damage of concrete structures in this paper. A cantilever is analyzed by finite element method, and the damage indices of the perfect structure and damaged structure are gained. Then Elman neural network is used to analyze the single damage and multi-damage quantification and damage location. Numerical simulation results show that Elman neural network method can make a better diagnosis for single and multiple damage identification. This method has certain guiding sense to damage identification in actual structures.
