They must take into account all features of the structure and its operating conditions. One of the perspective directions is the transition to "active systems", which include an active device - an actuator to influence the structure. Devices containing piezoceramic elements can be used as such actuators. In this work, a cycle of numerical experiments simulating the response of a 6.4 m × 4.4 m × 6.57 m reinforced concrete structure to the effects of a piezoelectric actuator was performed. At the first stage of this cycle, a numerical analysis of the interaction of the ceramic piezoelectric element with the structural elements was performed, which made it possible to determine the parameters of the piezoelectric actuator and the diagnostic impulse generated by it. At the second stage, the generated diagnostic impulse was used in solving a sequence of problems about the dynamic response of the structure to this impulse. As a result of modeling, the vibration portraits corresponding to the structure without defects and with defects in the form of cracks of various sizes were obtained. The results of comparing the sequence of obtained vibration portraits allowed to conclude on the possibility of effective use of the piezoelectric actuator as a diagnostic element in the active deformation monitoring system. © 2023 The Authors.
