Abstract EN
New approach is presented for controlling the structural vibrations.
The proposed active control method is based on structural dynamics theories in which multiactuators and sensors are utilized.
Each actuator force is modeled as an equivalent viscous damper so that several lower vibration modes are damped critically.
This subject is achieved by simple mathematical formulation.
The proposed method does not depend on the type of dynamic load and it could be applied to control structures with multidegrees of freedom.
For numerical verification of proposed method, several criterions such as maximum displacement, maximum kinetic energy, maximum drift, and time history of controlled force and displacement are evaluated in two- , five- , and seven-story shear buildings, subjected to the harmonic load, impact force, and the Elcentro base excitation.
This study shows that the proposed method has suitable efficiency for reducing structural vibrations.
Moreover, the uncertainty effect of different parameters is investigated here.
