Control of Seismic Vibrations of Structures Using Inactive Control Systems

One of the most important issues in structural engineering is finding ways to reduce the force to structural members of the building. The intense ground vibrations create lateral inertial forces in the structure, which makes the structure oscillate with a range proportional to its input energy. If the large share of this energy is spent on the structural motions, the seismic response will be considerably improved. Therefore, if a large amount of seismic energy can be wasted mechanically, the structure response can also be controlled without structural damage. The use of energy-dampening systems in buildings is responsible for the resilience of structural members during an earthquake and, as a result, prevents damage. One of the new and effective ways of coping with earthquakes is the use of a variety of active and passive dampers in the building industry. In the meantime, the selection of passive dampers is preferable because of low cost and more suitable technology than active dampers and their use in the country.
