“…In the case of applicability of the proposed method in realistic structures, using of the piezoelectric stack could be useful for a lot of reasons. In this way the method which has been introduced by Kamada et al [7] is proposed. In this method piezoelectric stack actuators are placed at the bottom of firststory columns in both sides.…”

“…This paper 2 Advances in Civil Engineering simplifies the selected modes into a unitary form by a simple method, so that the suitable position of the piezoelectric elements is achieved. Moreover Kamada and his coworkers modeled a four-story building, which was controlled by piezoelectric actuators, utilizing different algorithms [7]. Such study shows that floor accelerations could be reduced up to seventy percent.…”

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.

This research concerns active vibration control of a two-story model structural frame by using the method of loop shaping. Piezoceramic smart materials, in particular the PZT (Lead Zirconate Titanate) in the form of patches, are surface-bonded on the structure and function as actuators and sensors. Sensitivity charts are introduced to assist the control system design. A nonparametric system identification is performed to obtain the frequency response function of the model building. A loop-shaped controller is designed using sensitivity charts. The effectiveness of the designed controller is demonstrated by shaker table tests where data from four earthquakes is used for excitation of the structure. The experimental results clearly show that the loop shaping based controller reduces the vibrations experienced by the structure during seismic activities.

“…For example, Nkikkhoo presented the numerical analysis of active vibration control of piezoelectric smart beams and slabs [8,9]. Kamada et al carried out the active vibration control tests on frame structures [10,11]. However, little research has been done on the investigations of the active deflection control of concrete beam using piezoelectric actuator.…”

Abstract.A novel piezoelectric smart concrete beam composed of a concrete beam, a piezoelectric actuator and a counterforce device is developed and investigated. Based on the governing equation of 'actuating force-voltage' of piezoelectric actuator proposed by the authors, a nonlinear analysis program, in which material nonlinearity, geometric nonlinearity and local contact effects of cracked section are considered, is developed using Fortran language to analyze the piezoelectric smart concrete beams under active deflection control. Then active control tests are conducted to verify the developed program and good agreement is obtained. Moreover, a parametric analysis is carried out to investigate the influence of eccentricity of the actuator and the initial damage of concrete beam. The results reveal that piezoelectric actuators have greater active control effect when the eccentricity is larger while the recovery ratio is smaller when the initial damage of concrete beam is more severe.
