The maximum static load is increased in a step- wise manner, so that different degrees of damage are obtained. In between each static loading cycle, the modal parameters are measured using different techniques. This allows to draw conclusions about the sensitivity of the modal parameters to structural damage and about the suitability of the experimental techni
