Abstract
In this study, the dynamic substructuring of a benchtop three-storey building is realised where the two top storeys of the building are in real-time interaction with a simulated storey at the bottom of the structure. The challenging nature of this task is demonstrated by calculating the very limited stabilisable parameter domain if displacement-feedback control is used to connect the physical and virtual parts of the experiment. Instead of the direct feedback method, an iterative technique is applied to find the appropriate voltage input for the actuator that results in synchronous motion between the physical and virtual substructures and is free from the feedback-related instabilities.
