Smart Beams: A Semi-Analytical Method
One of the key challenges in structural engineering is to find better ways to control structural vibrations so as to better protect the structures from vibration-induced damages. Structural control methods can be classified into two main groups: passive control and active control. The basic role of passive control is to absorb or consume a portion of the input energy, thereby reducing the energy dissipation demand on the primary structural members and minimizing possible structural damage. On the other hand, in active control, the motion of a structure is controlled or modified by means of the action of a control system, which usually consists of sensors, actuators and controller, through certain external energy supply.
