The present thesis explores a newly proposed method, the Shaped Damage Locating Input Distribution (SDLID) scheme, for vibration-based damage identification localisation. The premise of the method is as follows: Given a structure is suffering from any type of damage, the steady-state vibration response, when applying the same load distribution, will be identical to that of the undamaged structure if the damage is rendered dormant. Based on this principle, the SDLID method operates by designing shaped inputs, which suppress certain steady-state vibration quantities. Damage is localised when the vibration signature from a damaged and undamaged structure, induced by the same shaped inputs, corresponds. Besides a numerical validation of the method, an examination regarding practical implementation is made by introducing experimental analyses of a six-story frame structure.
