Technology of Semiactive Devices and Applications in Vibration Mitigation

Civil engineering structures do not show the innovation rate which characterizes mechanical and aerospace engineering. There are three ingredients able to generate innovation: the design rationale, the construction materials and the quality process. The first ingredient has not seen revolutions in the last century, while the second suggested fascinating innovative solutions but they are still under durability exam to satisfy the long expected lifetimes which characterize civil infrastructure components. Therefore, certification and quality control were driving the innovation of the last half century within the usual framework of increasing the strength of the structure. It can be mainly obtained by making larger and larger sections, so that stiffer and more massive buildings results. One pay attention here to carrying capacity and, hence, the framework can be referred to as capacity design. This approach is unable to satisfy some needs which have risen in the last years, but the last decade introduced structural control technologies which offer very appealing solutions. In this field the objection on the power unavailability during events which seriously engage the structure, addresses the attention to passive devices, but a further class of semiactive control devices was soon introduced and is presented here.
