By equipping structures with appropriate actuators, sensors and microprocessors, it is possible to suppress actively the undesirable vibrations of the structures. Due to small energy requirements, the vibration suppression in large space trusses orbiting the Earth by controlling the elongations and contractions of length‐adjustable bars of the truss has been shown to be feasible both theoretically and experimentally. This method of vibration suppression is part of the ‘adaptive structures technology’. It can be used for suppressing the vibrations of a building subjected to earthquake or wind excitations, provided that the much higher energy and power requirements are met. In this work the use of gravitational energy of the mass of the building is proposed for active vibration control.
