Research on structural damage and fault diagnosis using measured flexibility matrices

HAN\ Xi,\ ZHONG\ Li (Department of Bridge & Structure Engineering,Chongqing Jiaotong University,Chongqing 400074,China)  
In this paper,the theoretical method of structural damage and fault diagnosis using measured flexibility matrices is put forward.Damage is found through a parametric updating of a large order static finite element model using a much smaller order measurement set.This method is accomplished without any model reduction or eigenvector expansion step.Numerical simulation results demonstrate that the method is capable of locating and quantifying structural damage.
