Damage parameters and input force estimation for simple frame structures sbjected ot unknown excitations
Shereena, O. A.
Damage parameters and input force estimation for simple frame structures sbjected ot unknown excitations - Vol.48(2), June-July - Chennai CSIR 2021 - 118-130p.
The present paper aims at estimating the damage parameters of the structures subjected to an unknown excitation. Damage parameters are characterized as the damage location and the reduction i stiffness. Typically, the damage identification is formulated as a joint state parameter estimation problem. Current work reformulates the problem, to estimate the excitation force simultaneously. The joint estimation problems are considered as nonlinear identification problems. The current study adopts a nonlinear identification algorithm that integrates an unbiased minimum variance estimator and an optimization scheme .....
