This paper gives an overview about how shape memory alloys can be used to the purpose of making tuned mass dampers adaptive and, thus, able to avoid mistuning with the primary system to be damped. Different configurations are taken into consideration, also performing detailed comparisons for given features of the tuned mass dampers. Finally,...

Operational Modal Analysis (OMA) is a widely employed technique used whenever dynamic characteristics of large structures or buildings are investigated. The main benefit of this strategy is that it does not require any artificial excitation, since only the system's outputs (acceleration, displacement) are necessary if the ambient excitation is...

In recent years, modal parameter-based techniques have gained particular interest in the development of structural health monitoring (SHM) strategies. Natural frequencies are the most commonly used dynamic parameter for damage detection in vibration-based SHM as damages manifest as a change in structural properties (stiffness or mass)....

This paper addresses monoharmonic vibration attenuation using piezoelectric transducers shunted with electric impedances consisting of a resistance and an inductance in series. This type of vibration attenuation has several advantages but suffers from problems related to possible mistuning. In fact, when either the mechanical system to be...

One way to enhance the performance of vibration control with piezoelectric shunt is to use a negative capacitance in the shunt circuit. This component is very effective and provides good results in terms of attenuation improvement without significantly increasing the complexity of the shunt network. However, negative capacitances are built...

Vibration attenuation by means of tuned mass dampers is a common practice in engineering since many years. Usually, their dynamic features are chosen so that a tuning on the modal characteristics of the system to control is achieved. Although such components can be very effective in reducing vibrations, they suffer of some drawbacks. The main...
