Research Abstract

In this study, we reviewed the classification and characteristics of structural response-control systems, and presented the advantages of active response-control systems. We then looked at the classifications of the control principles behind three systems, and also reviewed the required performance of control systems. To demonstrate how piezoelectric materials can be incorporated into smart material systems, we made vibration tests with scaled cantilevered beam and portal frame.
The results of vibration tests confirmed the validity of the control effect of the response-control systems and demonstrated the possibility to clarify the characteristics and performance of piezoelectric materials for use as actuators, sensors, and dampers in a smart material systems. Finally we speculated on the general concept and the prospects of using smart material systems in future building designs.
The performance of structural response-control systems depends on the control devices, which have been developed mainly from a practical-use viewpoint. When we reach a consensus on the requirements of future structural control systems, incorporation of smart materials into these systems will proceed. When that occurs, it will be important to develop reliable smart material technology and methods for evaluating the vulnerability of each component of structural response-control systems.
