The procedure requires prior knowledge of the fundamental vibration modes of the undamaged structure and mass matrix, either through experimental tests or through an accurate analytical model. An important advantage of this method is that very little experimental data is needed. To study the accuracy of damage identification under noisy conditions, we conducted numerical simulations of a multi-story, framed building. The new method was also tested by measuring the physical vibrations of a scale model under controlled damage conditions. Both variations of the method proved to be suitable, successfully identifying the location of damage and quantifying the stiffness reductions under various conditions.
