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.
