Abstract
This paper presents a comparative study including the theoretical modelling and the practical implementation of two types of well-known devices for structural vibration control. Firstly, a lab scale model for a two-storey building is dynamically identified. Then, a tuned mass damper (TMD) and an active mass damper (AMD) are described, modelled and assembled in the upper floor, both of them with similar effective mass. After coupling the dynamic equations, the experimental results are compared with the numerical ones and their performance is discussed. For modelling purposes, an experimental comparison and the corresponding computational simulation is carried out. Resulting assembled systems will undergo the same loading, consisting on an initial condition away from the equilibrium position and then released. The performance of each device is evaluated in terms of the time free oscillations take to return to rest (with accelerations within a 10% and a 5% band with regard to their maximum value). This is a relevant loading case from which interesting engineering conclusions can be drawn about not only the practical implementation of each proposed mitigation device but also about the computing and simulation capabilities.
