One-Step FE Model Updating Using Local Correspondence and Mode Shape Orthogonality

<div>MAC values between the mode shapes from the updated FE model and the mode shapes from the perturbed FE model. The updating was done using 10 LC expanded modes. The LC expansion used 12 model modes from the unperturbed system.</div>
