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

<div>MAC value between the modal vectors from the FE model updated with the one-step updating approach and the modal vectors from the perturbed FE model. The perturbation added to the original FE model corresponds to an increase of mass on every second element on an arm of the T structure by 300%.</div>
